Mingw-w64 is an advancement of the original mingw.org project, created to support the GCC compiler on Windows systems. It has forked it in 2007 in order to provide support for 64 bits and new APIs. It has since then gained widespread use and distribution.
The development and community are very active and welcoming with new contributors every month and simple installers.
initial Release: 2016-10-19
You can also look at the full list of versions.
Mingw-w64 interacts a lot with other projects in order to help everyone move forward. Contributions have been going to and coming from these projects:
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.
Updated imported headers to current Wine version.
What is the full list of your compilation flags?
Same result with gcc version 7.3.0 x86_64-posix-seh-rev0.
