Hi,
I just upgraded a server from 7.2-RELEASE to 7.2-RELEASE-p2. I'm
having issues with any port which links to libthr. This includes apr,
subversion, and sqlite, so it's pretty common for httpd to segfault. I
rebuilt libthr with debugging symbols, and I get the following
backtrace. This is the result of an 'svn ls' operation.
Program received signal SIGSEGV, Segmentation fault.

Previous frame inner to this frame (corrupt stack?)
Anyone have any suggestions? I've all ready rebuilt affected ports
without any change. Can I possibly rebuild the -p1 or -RELEASE version
of libthr without horribly breaking the system?
Thanks,
