Devel::bt Description

Devel::bt is a Perl module that, when enabled, registers a handler for certain types of fatal errors, like segmentation faults, and, once such an error occurs, prints a debugger backtrace to standard output before exiting the program.It is intended to be used to debug crashes in situations where running the failing program directly under a debugger is not possible, for example when trying to get more information from cpantesters or from users unfamiliar with gdb.SYNOPSIS $ perl -d:bt -MB -e'(bless \(my $o = 0), q{B::SV})->REFCNT' #0 0x00007f9c3215ab0e in __libc_waitpid (pid=, stat_loc=0x7fff4c5ffbe8, options=) at ../sysdeps/unix/sysv/linux/waitpid.c:32 #1 0x00007f9c319168c1 in backtrace () at bt.xs:129 #2 0x00007f9c319168ec in sighandler (sig=11) at bt.xs:135 #3 #4 0x00007f9c316c8ccf in XS_B__SV_REFCNT (my_perl=0x151c010, cv=0x177bfb8) at B.c:3360 #5 0x000000000057d5a0 in Perl_pp_entersub (my_perl=0x151c010) at pp_hot.c:2882 #6 0x000000000051a331 in Perl_runops_debug (my_perl=0x151c010) at dump.c:2049 #7 0x0000000000454ab0 in S_run_body (my_perl=0x151c010, oldscope=1) at perl.c:2308 #8 0x0000000000453d78 in perl_run (my_perl=0x151c010) at perl.c:2233 #9 0x00000000004230fd in main (argc=6, argv=0x7fff4c600788, env=0x7fff4c6007c0) at perlmain.c:117Product's homepage
