[Denemo-devel] Denemo crashes

[Richard Shann]

Eloi,

I was getting a crash when doing File->New. The crash vanished when I
turned the optimizer off. I re-compiled and noticed that keymapio.c had
some warnings about prototypes so I put the headers in keymapio.h, now
the crash has gone away. Before finding this consistent crash I was just
getting occasional crashes on startup, never the same twice.
Denemo used to be full of warnings on compile, but I have been reducing
them whenever I work on a file if I can; I hope this is another case
where it has paid off and that we don't have some threading bug lurking
in the code.
Below is the backtrace FWIW.
