not sure why you filed this under kdevelop, the backtrace suggests its a kompare bug. Reproduced. I reverted the last changes I made to Kompare (Which were the last changes to be made to kompare), and it still crashes. I am thinking that it might have been something in kdelibs or kdebase, since I updated those between the last time it worked and now. Aleix: do you remember updating either of those modules? Oh, BTW, if you KDevelop folks need some KomparePart API additions in 4.3.1, you'll have to get them into the 4.3 branch ASAP, I think it's going to be tagged in a few days. But if this integration is still unstable, maybe it should wait for 4.3.2 or 4.4? I'm using trunk, everything up to date. As I thought it was a problem in kdelibs. Appears to be fixed now. Never mind, after more testing the bug is still there. This all looks like memory corruption Fixed by commit 1010312 Isn't the fix actually http://websvn.kde.org/?view=rev&revision=1016093 ? Corresponding 4.3 branch commit: http://websvn.kde.org/?view=rev&revision=1016097 (note that the referenced trunk revision is wrong, this is actually a backport of 1016093). |
Version: (using Devel) Installed from: Compiled sources I since the last changes (I guess since the last changes in Kompare) I've been having this crash when comparing to base (Backtrace follows). I decided to apply the bug for KDevelop instead of Kompare because this didn't happen before, should be moved to Kompare I guess, anyway. If it's a problem on the instantiation or usage of Kompare just tell me and I'll try to fix it myself.
