0.4 toolchain broken
It appears that the 0.4 toolchain may be broken, as observed in ghc!7347 (closed):
C:/GitLabRunner/builds/0/908244/inplace/mingw/lib/gcc/x86_64-w64-mingw32/10.2.0/include/avx512fintrin.h: In function '_mm512_mask_reduce_mul_ps':

libbacktrace could not find executable to open
Strangely I wasn't able to reproduce this in a local build. This gcc issue looks relevant. Consequently I will try reverting gmp
back to 6.2.0-1
.
