Sry about that, I added the test case example code.
keith I added the test case example code.
Thanks. FWIW, my mingw32-g++ (MinGW.org Cross-GCC Build-20200531-1) 9.2.0 cross compiler reports the same ICE, when compiling your example:
Fork$ mingw32-g++ -S -masm=intel foo.cpp
during GIMPLE pass: *rebuild_cgraph_edges
foo.cpp: In member function 'void test3<T>::depart() [with T = const test1<long unsigned int (__attribute__((stdcall)) *)(void*)>]':
foo.cpp:55:1: internal compiler error: Segmentation fault

Please submit a full bug report,
with preprocessed source if appropriate.
Please include the complete backtrace with any bug report.
See <https://gcc.gnu.org/bugs/> for instructions.
whereas, with mingw32-g++ (MinGW.org cross-GCC-8.2.0-4) 8.2.0, it seems to compile cleanly.
Unfortunately, I am not a C++ expert, and don't consider myself qualified to pursue this further; your best course of action may be to file a GCC bug, on https://gcc.gnu.org/bugzilla/
Example Code: https://godbolt.org/z/e31raW
The code compiles fine in godbolt with gcc 9.2, but if compiled with mingw there is the following error:
