I just have to restart it.

Question is why does it takes all the memory, and why only ~12 gig
 on 32 gig system. Is there some limit from the OS? I am not aware of
 such.

Anyway, regardless of the system, there is some bug, it is perhaps only
 limited to Windows platform? I'll rebuild with debug options, do you want
 me to do something special, how do I debug it, or you can reproduce it?
 This is on Windows 10.

Restart Emacs? that's TRT when memory is exhausted..
