Re: How to debug a segfault?

[perlmonkey]

You can use gdb to debug perl. It is not ideal, but when you have core dumps it should help.

# start gdb
gdb /usr/bin/perl
# inside gdb run the script
run script.pl  
# after it segv's get the stack trace
bt

You can inspect the c data that was in memory at the time of the segv and probably figure out what caused the core dump. See the gdb man page for more details.

If you want to debug a segfault (or a memory leak) in perl itself, I like to use valgrind. It's popular on p5p as well.
