In theory BASEPRI should have been set to 0x10 by both bootloaders by
the time the application starts running. That the Windows-built
bootloader has not done that is unexpected. It looks like the actual bug
is in the Windows build. The Linux build is doing what I would expect.
So it looks like you have been fortunate not to trip over this issue
earlier.
The comparison of the executables that I mentioned earlier should help.
It looks like only the bootloaders may need comparing.
