Cf. https://forum.pellesc.de/index.php?topic=7974.msg29415#msg29415 (https://forum.pellesc.de/index.php?topic=7974.msg29415#msg29415), to start with.
Calling _popen in a multi-threaded 64 bit environment always returns NULL.
Am I missing something or is this bug still unfixed?
If so, is a fix in sight or should I devise a workaround? (32 bit is not an option for me.)
I confirm the problem.
It seems to be still there.
In the function _cenvarg() happen a memory violation. Memory pointed by RAX.
