Some news: The arithchk executable is working when compiled separately without any flags. So some flag is breaking them. The project builds and runs with tdm-gcc. `Building C object gdtoa/CMakeFiles/arithchk.dir/arithchk.c.obj cd /d C:\DEV\msys32\g33mgw\release\gdtoa && C:\DEV\msys32\mingw32\bin\gcc.exe -DINFNAN_CHECK -DMULTIPLE_THREADS @CMakeFiles/arithchk.dir/includes_C.rsp -ffp-contract=off -fPIE -Wall -Wextra -g -D_DEBUG -D_DEBUG -o CMakeFiles\arithchk.dir\arithchk.c.obj -c C:\DEV\msys32\g33mgw\gdtoa\arithchk.c...

I was able to find a solution. It turns out that you have to compile with the flag -fsignaling-nans.
