I tested this with AP 5.16, and SP 5.20.2, and as such assume the behavior to be present in all Perl versions, on Win7-64.

I tested it by running oneliners in a cmd shell and capturing the kernel events with procmon. As follows are the oneliners run, their truncated output and their respective event attributes. Please note the lack of quotes on the exec call​:

--

perl -e "my @​call = ('d​:/s p/perl/bin/perl' ,'-v'); system(@​call)"

This is perl 5, version 20, subversion 2 (v5.20.2) built for MSWin32-x86-multi-thread-64int [...]

I can't replicate. AP 5.16.3 x86, Win7-64.

Unlike system() and now list pipe open, Perl just calls the C run-time
_exec() for the non-threaded case.

So we could fix exec() by re-implementing it for Win32 (not for 5.22) but there
might be some back-compat issues.
