Probably, you were looking at the wrong sources (mingw-w64-binutils is on 2.38
on arch).

I just now decided to take the arch PKGBUILD and update it to 2.40 and it still
crashes. My debugger shows me this in pe-dll.c@1544:

    bfd_vma sec_vma = s->output_section->vma + s->output_offset;

Here are some variable values of interest:
s->output_section == NULL (which causes the SIGSEGV)
s->output_offset == 0
s->section == ".text"
b->filename == "_chkstk_ms.o"

Lemme know if you need more info (or want me to test a patch).
