Description Jean-Baptiste Faure 2013-05-05 14:52:00 UTC
Created attachment 78878 [details]
bugdoc which crashes the master

Open the attached bugdoc with the master (for me : Version:
Build ID: 19fe3be985a0d13c9818f920cb8e540ff658425 build on Ubuntu 12.04 x86-64)
It opens around page 17. 
Then scroll up with the scrollbar. 
At a moment LO freezes. If you can look at memory consumption you can see that LO is eating all the available RAM and swap. At the end it crashes.
To not have to wait too long, I launched LO in a terminal after the following command:
ulimit -S -v 3000000
(my PC has 4 GB of RAM) and with the option --backtrace. I will attach the gbdtrace.log I have got.

Best regards. JBF

I noticed this console log repeated a lot:
warn:legacy.osl:7269:1:sw/source/core/text/guess.cxx:497: Somebody, somebody, somebody put something in my string

I put it at New since there's a bt.
Comment 4 Arnaud Versini 2013-05-05 16:03:01 UTC
Julien, I have this patch for this problem (the trace), remove few traces but not all and seems better, but I prefere Miklos have a look before.
Comment 5 Arnaud Versini 2013-05-05 16:03:20 UTC
Sorry, forgotten the gerrit id :
Comment 6 Julien Nabet 2013-05-05 16:06:43 UTC
Arnaud: great! So let's wait for Miklos' answer:-) Perhaps both (trace + crash) are linked?

Verified with Version: Build ID: ef8a4af30a3261d92311c7c76af9cb9b123d7a5 with both the bugdoc and the original not anonymized document. Works fine.
