New version posted at https://github.com/bulk88/perl5-win32-api . I
didn't do anything specific for your crash. Please try it and report
back. It seems you crashed at the first cdecl function called, all the
previous ones were stdcall. On my 32 bit Strawberry Perl 5.12.3 all
tests passed.

Just to confirm, from the S Perl x64 bug ticket, is 32 bit S Perl
working and passing all tests for you?

Can you post a full run of the test suite on your 32 bit Strawberry
Perl? This is the last failing platform for Win32::API since Cygwin and
x64 Strawberry were fixed.

I decided to download 32 bit S perl 5.16.1 and so far, I think it is an
asm problem with the cdecl stack fixer/adder in call_i686.h. Variable
"words_pushed" was zero at the end of the Call_asm. I am still researching.

Bug identified, 32 bit Strawberry Perl 5.12 was using ebp parameter
addressing, 32 bit Strawberry Perl 5.16 is using esp parameter
addressing, since esp was moved around by "push"ing onto the stack, esp
addressing can not be used to fetch words_pushed to restore esp back to
its original position. keywords "frame pointer omission". Not sure how
to fix this yet since my knowledge of GCC is poor.

A fix was implemented, the fix only works on GCC 4.4 or newer, so S Perl
5.16 is covered. The fix is not publically posted yet.

The 32 bit Strawberry Perl 5.16 fixes are now available in Win32::API
0.73 on CPAN.
