An example .log file that causes my writes to become unresponsive

Problem description: 

I have an application which creates .log files. These files only contain some text so nothing special. Opening them with textedit, notepad or Word is not an issue. It works fine.

When I try to open them with libreoffice writer (V4.3.2.2) and they seems to have a certain size, it first ask in a window "import Dbase files" and which character set to use. After choosing the character set my libreoffice becomes not responding anymore and I need to force quit it.

In libreoffice version 4.2.0.4 the same thing happens only I get an error message:
Libreoffice 4.2 -Fatal error
std::bad_alloc

With smaller .log files which contain only few lines of text it works fine in writer.

I have added an example .log file which causes a crash on my system: it contains 319 lines and has a size of  21kb

Hi Joren,

Thanks to report this.
I see the same behaviour (Fatal error, Bad allocation) with LO 4.3.2.2 and Windows 7 Home Prmeium. If I change file extension to .txt, there's no issue to open it.
So I set Status to NEW and Hardware to All.

Regards,

Jacques

Unconfirmed with v3.3.4 under windows 7 x64.
Confirmed with v5.0.3.2 under mint 17.2 x64.

there's a single memory allocation of > 3gb in FResultSet.cxx:1289, that will never succeed on 32-bit.

but the real problem is that the type detection thinks that this is a DBase file, when it's clearly not.

can repro that in 4.1.0.4 already

well that contains a lot of typedetection refactoring...

fixed on master

I just emptied that exact temp folder because my SSD was filling up inexplicably. By then the folder was up to around 150 gb. As I am writing this my "aria-debug-8328.log" in that https://www.essayswritingservice.co.uk/ folder has grown maybe 0.5 gb. It is now 26 gb large. This makes no sense to me. What the hell is going on
