Was your Emacs compiled with "-gdwarf-2 -g3" compiler switches? If not, please reconfigure to use these and rebuild. It will be very hard to debug this without a reliable debug info. Also, please make sure you have the latest version of GDB available under Cygwin. If there's a version of cygwin1.dll with full debug info, please use that as well in your next trials. If none of the above helps to get a more meaningful backtrace, I'm afraid you will need to ask on the Cygwin list for more help. We need some way of getting a meaningful backtrace, to know where Emacs crashes, and I don't know enough about Cygwin internals to suggest how to get it, except with the above advice. > Lisp Backtrace: > 0x0 Lisp type 0 > Cannot access memory at address 0x0 > > xbacktrace > 0x0 Lisp type 0 > Cannot access memory at address 0x0 This is expected when C-level backtrace is garbled as above. Thanks.
