[Modules] GnuTLSClientVerify segmentation fault

[Jack Bates]

I am struggling a bit to use debugging symbols in mod_gnutls:

I tried building mod_gnutls with CFLAGS=-g like so:
http://cgi.sfu.ca/~jdbates/tmp/mod-gnutls/200809120/screenlog

However the first line of the backtrace is still: #0  0x00000050 in ??
()

How do I use debugging symbols in mod_gnutls?
