[richardleach]

I think a lot of these might be due to Perl_destruct bailing out early if it's the parent thread (or non-threaded build). If we define a couple of macros to implement this:

#if defined(__has_feature)
#  if __has_feature(address_sanitizer)
// code that builds only under AddressSanitizer
#  endif
#endif

They could then be used to skip early bail-out when ASan is in use.

[richardleach]

Also been meaning to check if there's a regular ASan smoker or not.

[Tux]

I think a lot of these might be due to Perl_destruct bailing out early if it's the parent thread (or non-threaded build). If we define a couple of macros to implement this:

#if defined(__has_feature)
#  if __has_feature(address_sanitizer)
// code that builds only under AddressSanitizer

please use C89 comment style only.
If not for safety, do it for consistency

#  endif
#endif

They could then be used to skip early bail-out when ASan is in use.

[richardleach]

@Tux - code above was just a rushed copy&paste from https://clang.llvm.org/docs/AddressSanitizer.html#conditional-compilation-with-has-feature-address-sanitizer, didn't mean to imply that's code to go directly into a PR.

Looks like we don't already have a __has_feature macro, so thinking there would be one new macro for that, then a separate macro that uses it to test for ASan. Sound ok?

[Tux]

Yes, sounds ok

[richardleach]

@atoomic - if you comment out https://github.com/Perl/perl5/blob/blead/perl.c#L948, are there any leaks left?

[atoomic]

@richardleach I'm not sure to understand the change you are suggesting, could you show me a diff?
thanks
