| Subject: | Using JavaScript.pm can cause the perl debugger to crash |
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?
