--- Comment #1 from Nathaniel Shead <nshead at gcc dot gnu.org> ---
Thanks for the report!  I haven't been able to reproduce on
x86_64-pc-linux-gnu, I guess I'll try to work out how to do a MinGW build this
weekend.

In the meantime, would you be able to share the exact command lines used to
build the std module and reproducer files?
