FS#179 - segfault in tm/timers?
User who did this - Ovidiu Sas (osas)

----------
Take a look at this gdb tutorial:
http://www.delorie.com/gnu/docs/gdb/gdb_56.html

Try to print the content of the memory before and after the cbp and see if there is something that you recognize there:
x/16xg cbp
x/16ag cbp

also, check the value of cb_lst->first to see if it's valid.

Most likely the memory was corrupted by another call and this particular call just crashed the server.
If this is the case, the core dump is not very useful because the crash doesn't capture the cause, only the effect :(
