When building with optimizations, are you passing the
-fno-omit-frame-pointer flag to GCC?
There was a discussion in emacs-devel about one month ago. Eli said:
This thread:
http://lists.gnu.org/archive/html/qemu-devel/2011-10/msg01697.html
suggests that it probably is. IIUC, there's an issue with setjmp in
the MS runtime not working when -fomit-frame-pointer is used, and the
MinGW GCC 4.6.1 turns on -fomit-frame-pointer by default when
optimizing. Since Emacs uses setjmp/longjmp _a_lot_, and in
particular C-g throws to the top level via this mechanism, it seems
like we have a smoking gun.
Perhaps rebuild Emacs with -fno-omit-frame-pointer, and see if that
helps.
