[rt-users] httpd2-prefork segfaulting on SLES11

Thu Nov 4 16:17:41 EDT 2010

Oh, there was a similar issue on opensuse related to hald-probe-inpu seg faulting. libc-2.11.2.so is part of the glibc-32bit package which was recently updated, build date of the rpm is 27 Oct 2010. I haven't backed out of the patch but maybe it's releated.
