Only DES & NT assembler seems to be problematic now. I'm hoping > Dhiru can produce core dumps for me. Nailed it. It turned out to be much worse than alignment and in hindsight it is obvious: Microsoft uses their own ABI, different from what anyone else uses. I think I have solved most of it (waiting for Dhiru to test, I'm just dry running). It might be that some invocation of EPILOGUE should be removed from the DES stuff - please review. magnum View attachment "win64-ABI-fixes.patch" of type "text/plain" (4068 bytes)
