------- Comment #16 from hosking at cs dot purdue dot edu 2006-08-31 05:37 -------
It turns out there were problems with aliasing in the trees generated by the
Modula-3 front end. There are multiple places where aliasing is used to
loophole values from one type to another, and this was probably causing the
problem. Having resolved my aliasing issues, I no longer see this problem.
Thanks for your help!
