Apparently, it doesn't. The backtrace is similar to the ones I used to get with the stock cygwin1.dll. This time Emacs crashed during startup, I didn't even have a chance to do anything before it disappeared. Backtrace is attached below. regards, Markus info threads Id Target Id Frame 10 Thread 0x3c4 0xfaf3003300001f80 in ?? () 9 Thread 0x1254 0x0000003300001f80 in ??
