[perl #129075] perl Perl_mess_sv() memory corruption
Message ID:
This appears to be a very complicated duplicate of RT #129027. This one spews debug output for about 30 seconds, and it doesn't actually segfault for me.

It's a null deref, the pointer is correctly zeroed and then incorrectly used (it's dereferencing 0x21 because that's the offset into the struct), so not a security bug. My patch in that ticket should also fix this, but I'm not sure because I can't actually repro.
