Comment 1 Tim Waugh 2006-03-22 14:18:11 UTC 
Changing version to devel.  FC5 ships with cups-1.1.23.
Comment 2 Tim Waugh 2006-03-23 13:42:35 UTC 
Please install the corresponding cups-debuginfo package, and then attach to the
cupsd process like this:

gdb /usr/sbin/cupsd 1104

(or whatever PID cupsd has)

Then at the (gdb) prompt enter 'continue'.  Go through the steps-to-reproduce
above, and when you get the (gdb) prompt again, please enter 'bt'.
Comment 4 Bernard Johnson 2007-06-26 22:00:20 UTC 
cups-1.2.11-1.fc8

I get an immediate segfault on i386:

# /usr/sbin/cupsd
cupsd: Child exited on signal 11!


Running under the debugger causes it to not segfault:

# gdb /usr/sbin/cupsd

Stracing it causes it to not crash as well.
