I just installed KDevelop for the first time on this computer, kdevelop-3.1.2 to be exact. When I try to start it, I get this: Connecting kdevelop-32230/KDevCore/projectClosed() PyDCOP connect kdevelop-32230/KDevCore/projectClosed()/f1() has result true Connecting kdevelop-32230/KDevCore/projectOpened() PyDCOP connect kdevelop-32230/KDevCore/projectOpened()/f2() has result true KCrash: Application 'kdevelop' crashing... along with the standard KDE crash popup window with a useless backtrace. The splash screen comes up, but that's as far as it gets before crashing. I know not what is going on. I shall provide an strace log after I finish filing this. Reproducible: Always Steps to Reproduce: 1. emerge kdevelop-3.1.2 2. try to start kdevelop 3. observe how it crashes and does what I mentioned above (or at least does on my computer) Actual Results: The stuff listed above.

Created attachment 66837 [details] An strace log created simply with strace -o log kdevelop I created the log with the simple command listed above. If you want me to create another log with more detail, like following all forks or something, just let me know.
Have you tried kdevelop-3.2.x? You can also try to compile with USE="debug" FETURES="nostrip" to get a backtrace.
I tried the same version of KDevelop, but compiled as you suggested. There is (far) more info output to the console, but for some reason the backtrace is still useless, although I don't remember if the line "Using host libthread_db library "/lib/tls/libthread_db.so.1" was there before. The mention of threads there leads me to share the fact that my computer has two Opterons, so it could be a problem related to two real processors instead of one pretending to be two, although whatever it is, it makes KDevelop crash every single time (so far). I previously experienced the same thing on a personal program a few weeks ago, with gdb being unable to generate a backtrace (with anything more useful than memory addresses), so maybe that's a gdb bug on at least AMD64 ('gdb doesn't work, at all' seems like a pretty big bug for me to just be discovering, but maybe it's already filed, or maybe people don't believe in debugging). I just recompiled gdb, and still no backtrace (maybe it's a problem with compiler, linker, assembler, who the heck knows, although I just recompiled gcc the other day, and I couldn't get a backtrace before that either). But regardless, KDevelop still crashes on startup. I'll attach its console output following this.

Maybe the crash is not in kdevelop code but in a linked library... btw: see also here https://bugs.kde.org/show_bug.cgi?id=95562
> Maybe the crash is not in kdevelop code but in a linked library... > btw: see also here https://bugs.kde.org/show_bug.cgi?id=95562 It's possible, but KDevelop seems to rely on every other library ever created, so a helpful backtrace would be nice. I'm going to file another bug about how I can't backtraces, and once that is resolved and I can get one, I'll post it here.
The crash is a known problem with 3.1.x when built with the hardened compiler. 3.2.x don't exhibit the problem; try one of those. They're currently marked ~amd64 so you'll have to add: =dev-util/kdevelop-3.2.1-r1 amd64 to /etc/portage/package.keywords to get it to install (or try 3.2.2 if you're feeling more adventurous). *** This bug has been marked as a duplicate of 68095 ***
I've got 3.2.2 running, and got the GDB problem figured out too. Shall we try to fix this version of KDevelop, now that I can get backtraces, or just leave it as is?
