Details:
I'm using the latest RPMs (SLC6) from the master branch. Running the
command:
xrdgsiproxy init -debug -cert /etc/grid-security/xrd/xrdcert.pem -key
/etc/grid-security/xrd/xrdkey.pem
occasionally segfaults (maybe 20-30% of the time) like this:

Here's the stacktrace from the core dump:
Core was generated by `xrdgsiproxy init -debug -cert
/etc/grid-security/xrd/xrdcert.pem -key /etc/grid'.

I also get the same thing occasionally when starting xrootd. I have another
stack trace for that, but I didn't have the debuginfo package installed at
that time:
Core was generated by `/usr/bin/xrootd -l /var/log/xrootd/xrootd.log -c
/etc/xrootd/xrd_cluster_005_gs'.

Both failures seem to happen in libcrypto, so I guess they are related.
