I see the same on Strawberry 5.26.0 (gcc-7.1.0), and on my own mingw-w64
build of 5.26.0 (gcc-7.2.0).
However, on my own build of 5.27.6 (gcc-7.2.0), the output of the test
program is correct.
Since the only difference between my build of 5.26.0 and my build of 5.27.6
is the perl source, I surmise that the perl source has already been patched
to fix the bug.
Cheers,
Rob
