--- Comment #2 from Jim Wilson <wilson at gcc dot gnu.org> ---
I've reproduced this problem with a RISC-V gcc-8.x compiler, and tracked it
down to the first patch for bug 81968, in comment #60.  With the patch
reverted, the testcase works.

The RISC-V testcase works with Linux hosted and Cygwin hosted toolchains, and
only fails for mingw32 hosted toolchains.  Maybe an LLP64 problem with the
patch?  I didn't see any obvious type error in the patch though.

I had to borrow a windows machine from our IT group to look at this, and they
have since taken the loaner back, so I don't have a machine at work I can use
to debug this at present.
