Trying out some more build options hasn't helped at all (debug builds hang just the same, and I see the same stack trace as Alex Gough reported; and builds without PERL_IMPLICIT_SYS also hang just the same), but unfortunately I've found another problem in the process :-(

It seems that win32/runenv.t fails tests 42-43 when perl is built with USE_IMP_SYS=undef (i.e. PERL_IMPLICIT_SYS is not defined, so there is no fork() emulation):

# Failed test 42 - expected number of elements in @INC for enough items so PERL5
LIB val is longer than 32k at win32/runenv.t line 246
# got "2"
# expected "2051"
# Failed test 43 - expected elements in @INC for enough items so PERL5LIB val is
longer than 32k at win32/runenv.t line 249
# got "D:/temp/bleadperl/t/lib ."
# expected "zzzzzzzzzzzzzzzz zzzzzzzzzzzzzzzz zzzzzzzzzzzzzzzz zzzzzzzzzzzzzzzz
[...]
zzzzzzzzzz zzzzzzzzzzzzzzzz zzzzzzzzzzzzzzzz D:/temp/bleadperl/t/lib ."
ok 41 - No errors when determining @INC for enough items so PERL5LIB val is long
er than 32k
not ok 42 - expected number of elements in @INC for enough items so PERL5LIB val
is longer than 32k
not ok 43 - expected elements in @INC for enough items so PERL5LIB val is longer
than 32k
Failed 2/43 subtests

Another strangeness in the behaviour here:

nmake test

hangs in various Module-Build tests.

But:

nmake test TEST_FILES=..\cpan\Module-Build\t\*.t

runs the Module-Build tests without a problem.

nmake test TEST_FILES="base/*.t ../cpan/Module-Build/t/*.t"

hangs in perl_mb_opt.t, as does:

cd ../t
.\perl harness base/cond.t ../cpan/Module-Build/t/perl_mb_opt.t

Yes, I found originally that the full test suite hangs (originally in
CPANPLUS tests and then again in Module-Build tests, but now seemingly
only in the latter), but when you try to look harder at individual hangs
then they don't hang any more :-(

I can reproduce the same result with the nmake command, which is useful
to avoid having to run the *whole* test suite every time, but the perl
harness command you've given runs without hanging for me :-/

I currently get three hanging tests in Module-Build (I'm ignoring here
the fork.t script which still intermittently hangs too): runthrough.t,
test_types.t and xs.t, and they all have the same call stack when
breaking into them when hung:
