I took the changes and all works fine if emacs is compiled with no
optimizations (--no-opt). If I turn on optimizations then I get the
following re-producable errors.
In such a case, it is necessary to track down where in Emacs the code
executes wrong, much as if you were looking for any other kind of Emacs
bug.
Once the problem is localized, you may find code that is not
well-defined C. Or you may find a line that is miscompiled. If it is
the latter, we would want to send a GCC bug report.
I still have here also a MSVC
and a two year old MINGW runtime environment with that I can do some
debugging.
If the problem does not happen with them, then they are irrelevant to
it. The way to find a bug is to debug the case that fails.
Investigating cases that don't fail won't tell you about the failure.
