FreeBSD pizzamig.bally.de 8.2-STABLE FreeBSD 8.2-STABLE #4: Fri Sep 30 11:07:25 CEST 2011     root at pizzamig.bally.de:/usr/obj/usr/src/sys/PIZZAMIG  i386
>Description:
gdb 7.3.1 crashes (segmentation fault) when you try to debug a multithread application. This patch solves this serious stability bug.
gdb 7.x versions are important, because advanced IDEs (like KDevelop 4) require at least gdb 7, they doesn't work with gdb 6.
