https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=194058 Bug ID: 194058 Summary: x11-toolkits/qt4-gui: bus error in qt_memfill32_sse2() on 9.3-STABLE i386 triggered by multimedia/vlc Product: Ports Tree Version: Latest Hardware: i386 OS: Any Status: Needs Triage Severity: Affects Only Me Priority: --- Component: Individual Port(s) Assignee: freebsd-ports-bugs@FreeBSD.org Reporter: ardovm@yahoo.it CC: kde@FreeBSD.org, multimedia@FreeBSD.org CC: kde@FreeBSD.org, multimedia@FreeBSD.org Bus error in x11-toolkits/qt4-gui triggered by multimedia/vlc. The function that triggers the bus error is qt_memfill32_sse2() in file painting/qdrawhelper_sse2.cpp:261. This happens on: FreeBSD myhost 9.3-STABLE FreeBSD 9.3-STABLE #88 r272279M: Mon Sep 29 09:10:30 CEST 2014 root@myhost:/usr/obj/usr/src/sys/GENERIC i386 Ports tree at revision 369691 CPU is an AMD Phenom 9550. I reported this problem on the kde@ mailing list on September 3rd but I received no answer. Since that day, I updated ports and world every week, but the problem is still there. The following description is from September 3rd, therefore it relates to the qt and vlc ports from that day. I was trying to start VLC today and it just printed out "Bus error". I recompiled debug-enabled Qt libraries (core and gui) and ran VLC through gdb: Program received signal SIGBUS, Bus error.
