So, it appears that it may have reached the end of it's main() 
function, then failed in the termination code.

That's got to be one of the least useful error messages, ever.

Did that popup message box not report a status code?  Knowing 
that might have been helpful.  It's possible that this is some 
sort of latent bug in the xsinfo.exe program itself, just as it 
may be due to some change in mingwrt or w32api.  Could you run 
xsinfo.exe under GDB, to determine where it is crashing?  Or,
build mingwrt and w32api from the repository, then run a git 
bisect over the changes since the last 3.x releases?

If you can do this, I'll hold off on the release of 5.0 for a 
couple of weeks, until we can glean some useful information 
about this crash.
