Test releases of the emacs, emacs-X11, and emacs-el packages

release of emacs-24.1.

Emacs users are encouraged to try it and report any problems to the
cygwin mailing list.
I'm experiencing regular seg faults, often while using gdb but not
always (switching between buffers is another big offender). I'm not
sure what other information I can provide, other than the EIP=610CF707
reported in the .stackdump file...
Caught one in gdb (no symbols, sadly):

Program received signal SIGSEGV, Segmentation fault.

HTH... I'm reverting for now (I can re-install if you've got specific
ideas to try out)

Thanks for testing. I'll try to make debugging symbols available so that you can get a better backtrace. It might be a few days before I get to it.

Do you have a recipe that will reliably produce a segfault for you? I've been using emacs-24 for months without any problems (as long as I build without gsettings support, as I did for emacs-24.0.96-1). But I haven't tested gdb-mi for a while.

You said you got segfaults even while not using gdb-mi. But did you get segfaults in an emacs session in which you didn't use gdb-mi at all in the entire session?
Good point. I probably had used gdb-mi at some point during every session that crashed.
