Another fairly common one is a Bus Error.
What signals result in the core dump? BUS SEGV PIPE ABRT? any others? Currently the module traps only SIGSEGV, hence the name. Can you really fork and fire up gdb on SIGBUS and other SIGs? > How about Debug::CoreStackTrace? The point of this module is that there is no core involved here ;) But I guess it's fine, assuming that the module gets extended to other signals as well. The module also includes Debug::SIGSEGVFault which dereferences a NULL pointer and causes SIGSEGV. how should it be renamed then? Debug::CoreDump? I guess I could release it separately. I bundled it up because it's needed to test Debug::SIGSEGVTrace. What do you think? BTW, meanwhile I put it on CPAN here: http://search.cpan.org/search?mode=module&query=SIGSEGVTrace > Have you looked at the sigtrap module? Your work may be a natutral > extension to that. It cannot be used, because the sighandler must be assigned on the C level. If you do it on the perl level, under 5.8.0 it won't work because of the way the signals handling is delayed in 5.8.0. __________________________________________________________________ Stas Bekman JAm_pH ------> Just Another mod_perl Hacker http://stason.org/ mod_perl Guide ---> http://perl.apache.org mailto:[EMAIL PROTECTED] http://use.perl.org http://apacheweek.com http://modperlbook.org http://apache.org http://ticketmaster.com
