Yes.  I think even GCC 13 needs some optimization disabled, see
bug#63365.

But debugging native-compilation on Windows with GCC 14 is not the
purpose of this bug report.  This bug report is concerned with crashes
you have at run time; that shouldn't be directly caused by a failure
to native-compile some Lisp file (because such a compilation is run in
a separate process).

So please build Emacs --without-native-compilation, and see if such a
build still crashes with those strange backtraces that show zero
addresses on the callstack.  If the build without native compilation
still crashes in a similar way, the problems with native compilation
are not relevant to this bug report.
