Comment:

    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:

$ 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
   55 | }

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/

Ticket details:

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:

MinGW\bin\g++.exe -g -o output.s -masm=intel -S -fdiagnostics-color=always example.cpp
during GIMPLE pass: *rebuild_cgraph_edges
example.cpp: In member function 'void test3<T>::depart() [with T = const test1<long unsigned int (__attribute__((stdcall)) *)(void*)>]':
example.cpp:55:1: internal compiler error: Segmentation fault
   55 | }
      | ^

example.cpp:55:1: internal compiler error: Aborted
g++.exe: internal compiler error: Aborted signal terminated program cc1plus

I hope the Test Case is described good enough.
