yes, if you compile the 32-bit version with the mingw-w64, it works.

problems occur only with the 64-bit version.

those interested can easily reproduce the problem, both on MSYS2 and Arch.

if your tests were indeed done with mingw-w64, the 64-bit toolchain, I guess it 
was an older version of qemu. all my tests were done with the latest git 
sources (2.2.92).

it's not only about my builds, the one included in MSYS2 has the same problem. 
those interested can also test it easily.

yes, the 64-bit Windows build prepared by Stefan Weil seems to be done with the 
old mingw-w32 on Windows, not mingw-w64.

the chances of succeeding this on my Mac are slim...
