James,

Yes, Hitech can cause trouble sometimes with local vars!  However, only
under very specific circumstances.  If you enable optimisations, the
compiler attempts to use as many redundant (for that function) SFR's as
possible to contain local variables, such as PRODH, PRODL, FSRx etc.  If
you include inline assembly that uses these registeres, the compiler
can't "see" it, so local variables can get scrubbed unintentionaly.

Mike
