What happens if you use libmap to point pthreads at libc_r using /etc/libmap.conf? You'll need something like this: [/usr/local/jdk1.4.2/] libpthread.so.1 libc_r.so.5 libpthread.so libc_r.so I've seen basically the same behaviour with Java. See: http://www.freebsd.org/cgi/query-pr.cgi?pr=threads/84778 Things that are utterly broken with libpthread (kse) often will work just fine with libc_r. But of course there are no bugs in libpthread and KSE works flawlessly.</sarcasm> On Fri, 11 Nov 2005, Gabriel Becedillas wrote: > Hi, > I'm getting a segmentation fault on FreeBSD 5.4 using pthreads.
