shibd segfaults because of libxerces-c (RHEL 6.6 SP 2.5.4)

[Heijdendael, Andreas]

Hi there,

Been trying to get shibboleth SP running on a RHEL 6.6 system but so far no luck.
Installation went well, although after investigation we found that libmemcached-0.31 was not installed.
After fixing that, still no luck.

What happens is the following:
Using the default /etc/init.d script the error message is that starting up shibd is failed.
Doing things manually doesn’t work either. Using shibd –t creates a segfault (core dumped) directly.

shibd[20018]: segfault at 3200000001 ip 00007f3b016929ff sp 00007fffd4ee9020 error 4 in libxerces-c-3.1.so[7f3b0139a000+3d3000]

Above line appears in syslog.

After comparing installation between the RHEL 6.6 installation (faulty) and a CentOS 6.6 (working) installation we noticed that the libssh2 is missing from the list of dynamically loaded libs (ldd /usr/sbin/shibd) but that hardly explains why shibd segfaults on libxerces, correct me if I’m wrong.
What was also noted, was that shibboleth version on RHEL is 2.5.4-3.3 instead of 2.5.4-3.4 on CentOS. Changelogs, however, do not mention anything about bugfixed concerning libxerces or libssh2.

I really need help here… Tried using GDB but  that only gave me the following:
