--- Comment #11 from Florin Saftoiu <florin.saft...@soft-to-you.com> --- Hi Nick, Sorry it took so long, I finally got some time, so I compiled the msys2 binutils-2.32 package from source and ran it in GDB. Here's my GDB session : $ gdb --args /c/work/projects/soft-to-you/osdev/gcc/src/MINGW-packages/mingw-w64-binutils/pkg/mingw-w64-x86_64-binutils/mingw64/bin/ld.exe -o test_64_broken.exe -L/mingw64/x86_64-w64-mingw32/lib test_64_broken.o -lkernel32 -luser32 GNU gdb (GDB) 8.3 Copyright (C) 2019 Free Software Foundation, Inc.
