Comment 2 for bug 1597450

Zesty 0.8.0-1 is the current FTBFS. I was able to progress the debugging a bit and something is scribbling on the stack. The problem I'm experiencing is gdb disables breakpoints in the shared lib I need to examine the stack canary address.

Starting program: /usr/sbin/apache2 -X -f /home/bmorton/mod-gnutls-0.8.0/test/tests/24_pkcs11_cert/apache.conf -k start
[Thread debugging using libthread_db enabled]
Using host libthread_db library "/lib/i386-linux-gnu/libthread_db.so.1".
AH00558: apache2: Could not reliably determine the server's fully qualified domain name, using 127.0.1.1. Set the 'ServerName' directive globally to suppress this message
warning: Temporarily disabling breakpoints for unloaded shared library "/usr/lib/i386-linux-gnu/libp11-kit.so.0"
