Sorry, I'm not sure that's the right solution in that case. We should
try to understand why the problem happens in the first place. E.g., I
don't see it here (but I don't use MinGW64 or MSYS2).

The only thing you might be missing is the fact that we passed the
compiler the -Walloc-size-larger-than=9223372036854775807 option.
