--- Comment #8 from Alex Weslowski <aweslowski at gmail dot com> --- (In reply to Richard Biener from comment #6) > Illegal instruction is usually coming from gmp/mpfr which might be linked > statically into your GCC binary on mingw. 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).
