I compiled MRI 1.8.7-p358 for myself on Windows 2003 SP2 system with gcc version 4.6.2 (GCC) (latest stable mingw), and it crashes if ruby code try Win32API call.

Steps to reproduce:
1) Compile ruby 1.8.7-p358 with default install MinGW with /configure --enable-install-doc --enable-shared --with-winsock2
2) Install it with make DESTDIR=d:/somewhere/in/a/filesystem
3) Try run attached ruby code

Expected result:

something like:
"C:\\Documents and Settings\\All Users\\Application Data"

Actual result:
win32test.rb:8: [BUG] Segmentation fault
ruby 1.8.7 (2012-02-08 patchlevel 358) [i386-mingw32]
