Subject: Using JavaScript.pm can cause the perl debugger to crash
Download (untitled) / with headers
text/plain 1.4k
When using JavaScript.pm, the perl debugger can crash. This appears to happen when the JavaScript context is destroyed. The "Devel::Profile" manpage says, under "Bugs": "Some buggy XS based perl modules can behave erroneously when run under the perl debugger. Since Devel::Profile uses the perl debugger interfaces, these modules will also behave erroneously when being pofiled." I've scoured the net for more information on what bugs/glitches could cause this, but no luck yet... but it looks like running under the debugger may be making perl attempt to double-free an SV? Program received signal SIGSEGV, Segmentation fault.
