Summary0015840: Random crash in IDE with gtk2 (Ubuntu Lucid) :TApplication.HandleException Invalid floating point operation
DescriptionLazarus is latest SVN r23772.
Platform is Ubuntu Lucid up-to-date as of today (2010-02-24 if Mantis doesn't save this info).
I randomly get this error, usually when starting Lazarus or when starting the project (debugging).

Seems like a bug in the gtk theme, but doesn't happen in any other application and seems to occur with any (several, at least) theme.
Maybe the something regarding the form size?

I can confirm. I tried to debug it, but the error happens inside the gtk. Probably some dangling pointer/buffer overflow.

I've even installed gtk sources (even though I'm not sure it'll help much), but I'm having some difficulty in reproducing it and never get to reproduce the bug while I'm debugging Lazarus inside Lazarus :-/
(I'm not very experienced in plain gdb yet, and seeing the source code would be way better)

Mattias, Paul suggested that changing the exception mask for the library (and said this would be a fix, not a hack, and that fpc needs this in some situations). This seems to work:

This later fix solves it for me too.

I tested my upload for Ubuntu with and without this patch and when I want to open a project, lazarus-ide was hanging without the patch, but proceeds as expected with the patch. (The issue for me is related to a buggy qtcurve library, but it helps if lazarus-ide doesn't hangs.)
