Hi Vikas,

I also get the corouting assertion when I start my precompiled QEMU
binary with an ISO image (Debian i386 netinstall).
The error can be reproduced with Wine on Linux, too.

There is no error when QEMU was configured with --enable-debug (which
disables optimisation),
nor is there an error when I just run the BIOS code (no disk, no cdrom).
This explains why I did not
notice the regression for Windows earlier.

So we have to find the first version which shows that regression, either
by testing older installers
or by running git bisect.

Cheers,
Stefan
