Description gzernmplatz 2017-01-23 19:56:05 UTC
Attached spreadsheet has 643202 lines and 9 columns. When I select 643201 cells (most of last column) and press ctrl-c, LibreOffece crashes. I tried this both in version and and it ALWAYS crashes.

Steps to Reproduce:
1. Load attached spreadsheet (takes time)
2. go to line 2, column I
3. press shift-ctrl-End to select cells
4. press ctrl-c
5. Wait - LibreOffice first freezes, than crashes.

Actual Results:  
LibreOffice crashes

Expected Results:
Content in clipboard

Reproducible: Always

No, we don't have time to build stuff in order to test bugs. You could use to give us the file

For reference, the contents of the attached text file:
Tried to attach file several times but failed and saw it is bigger than size limit. How to make similar file:
1. New Spreadsheet
2. Input some letters as captions in the first line, first 9 columns
3. Under that, get some natural numbers in the range 10 to 28 in the first 8 columns until line 643202 - you could use random numbers, for example.
4. cell I2, input the formula:
5. Select until end of file and fill, so the formula is in the whole 9th column
Hope that works. I will try to zip my file and attach it - I guess its size is the reason for the crash, because I keep getting crashes with big spreadsheets.

You can download the spreadsheet from
I'm sorry for messing it up. By now I also have a zipped version that is under the size limit but zipped in Linux. Would it be useful to attach it?
Comment 7 MM 2017-01-25 22:27:34 UTC
Unconfirmed with v5.2.5.1 under ubuntu 16.04 x64.
Confirmed with v5.2.5.1 under windows 7 x64.

Hangs for some time with ubuntu, but no crash. Seems windows only ?!
All cells without the IF's don't hang, copied fast.

I cannot reproduce the crash on my Win debug build. The spreadsheet becomes normal after Ctrl-C and waiting for a moment. Using laptop from 2012 with 8GB mem and i7 CPU.

test case - first needs to be expanded

This spreadsheet can be used for testing by first filling the columns (ctrl-d). I can't upload a complete version because my attempt to produce it made my LO crash.
Comment 13 gzernmplatz 2017-07-18 17:04:48 UTC
This bug seems to be very sensitive to file size. When I deleted about half the lines of the spreadsheet it was gone afterwards. So I ask you to do the following steps: 
Load rand1.odt
select the stuff inside
press ctrl-shift-ArrowDown
press ctrl-d
If this does not make your LibreOffice crash, now you have a bigger spreadsheet than mitB2. You can of course fill a few columns to the right, too. Could you please try this and tell us wether the bug occurs?
Comment 14 Buovjaga 2017-07-18 18:14:28 UTC
It is clearly due to running out of memory. I have 32 gigabytes of mem and I could even fill right all the way to column O.

Does the crash ever happen, if you set the undo steps to 1 in Tools - Options - LibO - Advanced - Expert config: org.openoffice.Office.Common/Undo ?
Comment 15 gzernmplatz 2017-07-26 07:27:40 UTC
Yes, it does. In some cases it says "Bad Allocation", in some it just says LO does no longer work due to a problem. Furthermore, I loaded the file and did not make any changes to it before trying to copy. Instead of crashing, LO could just say something like "can't do that because memory runs out".
Comment 16 Xavier Van Wijmeersch 2017-07-26 20:34:47 UTC
test with rand1.odt  no crash, have only 8gig of memory, use only 3.5 gig
saving the file very slow

Comment 17 Timur 2017-11-08 12:20:37 UTC
LO 6.0 alpha 32-bit - Win 7 64-bit:
1st try: LO had dump on fileopen (seen with procdump)
2nd try: LO didn't crash on copy from Description but there was dump on copy (seen with procdump)
3nd try: LO consumes 1 GB on fileopen. Used 1,6 GB on copy and than crashed, document recovery, no crash report.
So I can confirm crash, but cannot confirm crash is about running out of memory. Even saving file stayed at 1 GB, although it was rather slow. 

Telesto had:
FAULTING_SOURCE_LINE:  c:\cygwin\home\tinderbox\master\sc\inc\formulacell.hxx
SYMBOL_NAME:  sclo!ScFormulaCell::GetMatrixFlag+a
FAULTING_SOURCE_FILE:  c:\cygwin\home\tinderbox\master\include\formula\token.hxx
SYMBOL_NAME:  forlo!formula::FormulaToken::IncRef+12
I had on load:
SYMBOL_NAME:  sal3!osl_acquireMutex+f
and on crash:
SYMBOL_NAME:  sclo!ScMatrix::IsValueType+79c1
and on Comment 13 (that's not really clear) select:

Dear gzernmplatz,

To make sure we're focusing on the bugs that affect our users today, LibreOffice QA is asking bug reporters and confirmers to retest open, confirmed bugs which have not been touched for over a year.

There have been thousands of bug fixes and commits since anyone checked on this bug report. During that time, it's possible that the bug has been fixed, or the details of the problem have changed. We'd really appreciate your help in getting confirmation that the bug is still present.

If you have time, please do the following:

Test to see if the bug is still present with the latest version of LibreOffice from

If the bug is present, please leave a comment that includes the information from Help - About LibreOffice.
If the bug is NOT present, please set the bug's Status field to RESOLVED-WORKSFORME and leave a comment that includes the information from Help - About LibreOffice.

Please DO NOT

Update the version field
Reply via email (please reply directly on the bug tracker)
Set the bug's Status field to RESOLVED - FIXED (this status has a particular meaning that is not 
appropriate in this case)

If you want to do more to help you can test to see if your issue is a REGRESSION. To do so:
1. Download and install oldest version of LibreOffice (usually 3.3 unless your bug pertains to a feature added after 3.3) from

2. Test your bug
3. Leave a comment with your results.
4a. If the bug was present with 3.3 - set version to 'inherited from OOo';
4b. If the bug was not present in 3.3 - add 'regression' to keyword
