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 | } | ^ 0xbc5ecf crash_signal ../../src/gcc-9.2.0/gcc/toplev.c:326 0x9f077b obj_type_ref_class(tree_node const*) ../../src/gcc-9.2.0/gcc/ipa-devirt.c:2026 0xe10556 virtual_method_call_p(tree_node const*) ../../src/gcc-9.2.0/gcc/tree.c:13009 0x8489d1 cgraph_node::create_indirect_edge(gcall*, int, profile_count, bool) ../../src/gcc-9.2.0/gcc/cgraph.c:968 0x84dd1a cgraph_edge::rebuild_edges() ../../src/gcc-9.2.0/gcc/cgraphbuild.c:421 Please submit a full bug report, with preprocessed source if appropriate.

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 Status: Reporter: thekbro Owner: (None) Type: Issues Status: Open Priority: 5 - Medium MileStone: (None) Component: GCC Severity: 5 - Medium Resolution: None --------------------------------------------------------------------- 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 Im using: Windows 10, 64 bit GCC Version Using built-in specs.
