Binutils 2.30 can't compile AVX code with GCC 8.3 #5328
Description
Binutils 2.30 cannot process all files generated by GCC 8.3.
See for example: https://ci.appveyor.com/project/RubenVanBoxem/skui/build/job/jlkmhpoa15kwvkbq#L1208
These errors are solved by using binutils 2.32:

Probably the compiler switch

As per #4317 (comment) 2.31 and 2.32 are broken in different way.

The compiler switch is a workaround, not a solution, so it can't be "needed" (and it's not with Binutils 2.32).
As for the Clang build issue: if the ld bug is not fixed on binutils master, it should be reopened.
Is there a way to get e.g. binutils-git as a built package in MSYS2? That would avoid my issue without adding hacks to my code.

Binutils 2.32 with the fix for #4317 have been uploaded.

Is this fixed now?
