Set PERL_DESTRUCT_LEVEL=2. Also, in your build process, make sure to run 'make test' after each supposedly successful compilation and see if every module is actually building correctly. Very basically, it means your program is trying to access a memory area it is not suposed to. 2. https://ubuntuforums.org/showthread.php?t=2071988&page=2 Luckily, you can download Debug::DumpCore from CPAN, which does a very simple thing--it segfaults when called as: use Debug::DumpCore; Debug::DumpCore::segv( ); Debug::DumpCore::segv( ) calls a function, which calls another function, which

That way you'll know if a file fails to open.

For example if we want to debug the function PerlIOAPR_open which resides in APR/PerlIO/PerlIO.so we first load it and then we can set a breakpoint in it. The trick is to break at apr_dso_load, let it load libmodperl.so, then you can set breakpoints anywhere in the modperl code: % gdb httpd (gdb) b apr_dso_load (gdb) run -DONE_PROCESS [New facebook google twitter rss Free Web Developer Tools Advanced Search  Forum Programming Languages Perl Programming Segmentation Fault (core dumped) while connecting thru DBD::Oracle Thread: Segmentation Fault (core dumped) while connecting e.g.: (gdb) macro expand pTHX_ expands to: PerlInterpreter *my_perl __attribute__((unused)), (gdb) macro expand PL_dirty expands to: (*Perl_Tdirty_ptr(my_perl)) For each library that you want to use this feature with you have to
