--- Comment #46 from jeremy rutman <jeremy.rutman at gmail dot com> --- I don't know if this is relevant but a certain gcc I was using lately seems to do fine compiling one of the autogenerated files in question (an AES128 encrypt file) , but quits unexpectedly when I try compiling a second (the corresponding AES128 decrypt) version: gcc.exe (x86_64-win32-sjlj-rev0, Built by MinGW-W64 project) 5.1.0 Copyright (C) 2015 Free Software Foundation, Inc. $ C\:/Program\ Files/ANSYS\ Inc/v241/SCADE/contrib/Msys64/mingw64/bin/gcc.exe -v -pedantic -Wall -Wextra -Wwrite-strings -g3 -I"C:\Program Files\ANSYS Inc\v241\SCADE\SCADE\.\libraries\SC65\libmathext" -I"..\cryptol_aes" -I"..\cryptol_aes\dec" -I"..\cryptol_aes\enc" -I"." -I"C:\Program Files\ANSYS Inc\v241\SCADE\SCADE\." -I"C:\Program Files\ANSYS Inc\v241\SCADE\SCADE\.\include" -I"C:\Program Files\ANSYS Inc\v241\SCADE\SCADE\.\include\C" -I"C:\Program Files\ANSYS Inc\v241\SCADE\SCADE\.\include\Ada" -I"C:\Program Files\ANSYS Inc\v241\SCADE\SCADE\.\lib\Ada" -pedantic -DBUILD_DLL -DSIM -DWIN32 -D_CONSOLE -D_MBCS -c -ansi -std=c99 -m64 "..\cryptol_aes\dec\aesDecrypt.c" -o "win64\aesDecrypt.o" Using built-in specs.

I don't see any errors and I think the compiler just quit unexpectedly. That same command but for aesEncrypt.c completes correctly (and quickly) , creating the working .o file.
