I just wanted to report that I reported this problem on another thread, but just found this one. I continue to experience the bug. I have just installed 64 bit cygwin with emacs X11 in a new Windows 64 bit virtual machine. The X Server is Cywin X11 in a 64 bit cygwin install. Any attempt to run emacs X11 results in > Fatal error 12: Bad system callBad system call (core dumped) I have used the stack size suggestion to make it unreasoably large (310378496 (0x12800000) bytes) to no effect. Hope this gets solved soon Thanks Gulliver -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: http://cygwin.com/docs.html Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple
