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 | }
      | ^
