The problem is https://github.com/bulk88/perl5-win32-api/commit/fe878eab5bd0b52d953e209105e441eb795b0b7e turned "long_ptr" from signed into unsigned, so the 4 byte int is zero extended to 8 byte IV, not sign extended. That commit and the whole long_ptr usage needs a review to figure out how to fix this and not break something else.
