Version: 1.2 gentoo CVS ebuild (using KDE KDE 3.3.2) Installed from: Gentoo Packages Compiler: gcc version 3.4.3 20041125 (Gentoo Linux 3.4.3-r1, ssp-3.4.3-0, pie-8.7.7) AMD64 OS: Linux Similiar bugs are listed with xine, but I believe this is differnt. If amarok is started with xine engine it segfaults and a "squeel noise" is heard on the speakers right before it does this as it tries to play a mp3. I am using amarok CVS and xine-lib 1.0, I have tried previous versions of amarok (1.2.1 and 1.2.2) and numerous xine-libs (1_rc6 and 1_rc8), they all segfault. I believe the bug is xine's fault, but all the same, amarok should not crash and instead print an error message. Any suggestions on how to debug this further or if I should take it to xine people would be appreciated. I believe this to be an AMD64 specific bug.

The crash is inside xine indeed. Asking for amaroK not to crash if xine does is like asking gravity to take exception to you just for a few hours. If xine crashes after we've dynamically loaded it, amaroK also crashes, it is as simple as that.
Thanks for the info. I will try and take it over to xine.
