Problem compiling on Win64 using GCC

Compiling the sample big.cpp
Using either:
g++ -o big.exe -ID:\programming\ttmath-0.9.3 big.cpp
gcc -o big.exe -ID:\programming\ttmath-0.9.3 big.cpp
Results in this monster of a response (Warnings & Assembler error):
gcc -v & g++ -v return:

Is this a known problem? Do I have to use another compiler?

Make sure you are using 0.9.4 (2019.07.31) version. A similar bug was fixed there.
