It seems that the Cygwin shell is eating exceptions (sigsegv or similar signals?). Is there a way for me to disable this behavior? I believe you want the reverse of this program: https://github.com/msysgit/msys/blob/master/winsup/utils/error-mode.c error-mode can make the popups go away (getting cygwin behavior on msys), but it should be possible to modify it to make the popup appear instead. I think...
