The backtraces are useless, gcc cannot generate usable backtraces with -fomit-frame-pointer. Which means this bugreport only says "konqueror sometimes crashes", which in turn means this bugreport doesn't provide any useful information and is useless, sorry.

So what do I do? I will change the CFLAGS setting.

And then: Recompile gcc or recompile KDE? Or both?

Recompile KDE and Qt. Preferably even with -g

I've recompiled Qt and KDE, but now the problem is gone... Cannot reproduce it anymore.

Great! Don't you just love when that happens?

BTW, I saw you used -O4. Try less aggressive optimisations and see if it stabilises for you.

Indeed I love it when I see that :)

But where do you get the -O4 from? My CFLAGS says -O2...

Uh... It's there... it's just that there's an "2 -march=pentium" between the O and the 4.

Sorry, my bad. No more bug hunting before morning coffee.
