I've emerged kmail 1.8.3 with KDE 3.4.3 (splitted ebuilds) and gcc-4.0.2. I had no problems compiling and all apps are runnung well - except for kmail. It always crashes when I try to check for new mail. It crashes regardless the type of mailbox (IMAP, or POP3). I made a strace and here it is: kmail: processNextCheck, remaining 1 kmail: for host pop3.freenet.de current connections=0 and limit is 0 kmail: connection limit reached: false kmail: processing next mail check for Freenet kmail: check mail started - connections for host pop3.freenet.de now is 1 kmail: Data: <End> kmail: [void KMAcctExpPop::slotJobFinished()] stage == List kmail: Data: <End> kmail: [void KMAcctExpPop::slotJobFinished()] stage == Uidl kmail: Length of message about to get 4250 kmail: Length of message about to get 3313 kmail: Length of message about to get 3408 kmail: Length of message about to get 3754 kmail: Length of message about to get 2871 kmail: Length of message about to get 3056 kmail: Length of message about to get 5887 kmail: Length of message about to get 7274 kmail: Length of message about to get 2738 kmail: Length of message about to get 4614 kmail: Length of message about to get 2835 *** KMail got signal 11 (Crashing) KCrash: Application 'kmail' crashing... I've compiled kmail and kdebase-kioslaves with very sane C(XX)FLAGS and USE="debug" (not the ones in my emerge info), but the crash remains and the backtrace is useless. If you need more info I'll recompile kdelibs with USE="debug" to get a better bt. BTW: I'm a long time KDE user and kmail 1.8.2 worked flawlessly yesterday. I didn't change any configs...

To get a usable backtrace remove -fomit-frame-pointer from your compiler flags and do FEATURES="nostrip" USE="debug" emerge kmail
> To get a usable backtrace remove -fomit-frame-pointer from your compiler > flags and do FEATURES="nostrip" USE="debug" emerge kmail I did so but the backtrace is (nearly?) the same as before, except that there are no [symbols not found] messages anymore... Using host libthread_db library "/lib/libthread_db.so.1". `system-supplied DSO at 0xffffe000' has disappeared; keeping its symbols.

Maybe the backtrace is better then.
Created attachment 70660 [details] Backtrace with non-stripped kdelibs, kmail, {kdebase,kdepim}-kioslaves Here's the promised backtrace.
This bug [1] pointed me to the solution. After recompiling mimelib (3.4.2) kmail works again. Because here the version number hasn't increased I didn't recompile it with gcc4 and the one compiled with gcc-3.4.4 didn't work together with the rest. [1] http://bugs.kde.org/show_bug.cgi?id=15774 I think this bug can be closed, but decide on you own.
I was just about to ask if you were sure you had compiled ALL the KDE stuff with GCC 4 - otherwise stuff will break. I am trialling it on my laptop. Closed now.
