No one, but they need to know about issues like this in order to do something
about them. Above you said that this was "not possible" to fix for mingw. If
you really meant "this would require changes in the mingw runtime", perhaps you
should have said that. Then, even if you are not motivated to approach the
MinGW developers to effect such changes, someone else (e.g. me) could have.

Testing, I cannot reproduce either on a different machine, so probably
something just went wrong with my install here.  Sorry for the noise.
