I compiled both of the preprocessed source attachments and could not reproduce
your failure using a recently built gcc 13 cross compiler from linux to
x86_64-w64-mingw32.  I used no options, "-O3 -Wall -fno-strict-aliasing
-fomit-frame-pointer-funroll-loops -fPIC", and "-O3 -Wall
-fno-strict-aliasing" based on your command lines.

Is it safe to assume that this is no longer an issue?

This may indeed be the case. Also happens in GCC 7.2.0, which may indicate bug
in external program. GMP/MPFR/MSYS2/Windows/other. Pasted is a similar or same
error in 7.2.0. Attached the relevant preprocessed file to this bug (even
though this bug is marked 6.4.0).

Illegal instruction is usually coming from gmp/mpfr which might be linked
statically into your GCC binary on mingw.

Please note, this appears to be fixed (hopefully) in GCC 7.2.0. Either that, or
my version of GCC 6.4.0 is borked. (Or, it may be an intermittent error, I
suppose.)

Hi, will attach the mpker.i file to this bug. The zip file has also been
updated. Check the O6.1-none-msys_nt directory, I think.
