mingw-w64.org compilers do not exhibit this error, either on 32-bit or 64-bit builds, nor am I seeing this test failure on Cygwin or Linux.

Yes, I am just as confused by this as you are.

Yes, I am just as confused by this as you are.

Nor does it occur on non-ming builds. It smells like a compiler error.
I suggest turning off optimization and see what happens. If it
continues, try it with something like valgrind, if available.

Is this still a problem? https://github.com/Perl/perl5/commit/cd2d26f70ace8c111e4ba473b48847edcbc48c16 made a fix to a similar problem.

If I don't hear back in 30 days, I think we should close this ticket
