I have encountered the following bug, but I'm not sure where the fault
lies. Please post info if you have similar experience.

I have Lattice 3.03 and kickstart 1.1.

The C program in question has two INT register variables, and one
pointer register variable.
The variable which occupies register D7 is being clobbered
by a called routine which calls DoIO with commands for the serial.device.

By simply changing the declaration from 'register int' to 'int'
I avoid the problem; but there is a lot of code available using
register variables and I wonder if anyone else has this problem.
(Come to think of it, my copy of MicroEMACS has a suspicious spurious bug)

Thanks for any info, I'll post more when I find it; but I may be
awhile in getting to it.
