For the bug report summary it looks like you assume this crash has to do with the size of your callgrind file. How large is it? Can you make it available to me for reproduction of this issue?
Actually, when I tried to open it again it worked. Dunno if that says anything about whether it's the size of the file that was the problem. I no longer have the exact file that caused the crash - Apache has written over it - but I've generated another that should be the same. It's just over 150Mb. Please let me know when you have it so that I can remove it from my Ubuntu One storage. http://ubuntuone.com/p/XVq/
You can remove it, thanks. Hmm. 150 MB is not really that large. It will definitely not trigger any out-of-memory situation, even not with 32bit (and you are obviously at 64bit). Anyway, I can not reproduce the crash. Does this crash for you? When does it crash? Directly after/at loading the file? Or after selecting a function? I can not really make much out of the backtrace above. If the crash produces the same backtrace, you could try the following: add before functionlistmodel.cpp, line 404 the following: "if (!f || !f->data()) return;" and recompile. And if it still crashes, it must be somewhere in "FunctionListModel::getInclPixmap()". Sorry, as you probably can see, I am a little lost with this bug report...
