Yes, but the bug is not correlate with the reference parameters.
I can reproduce it without parameters.

Another workaround is:

STORE m.This TO m.oObjectRef.myReference


But when you reproduce it with out the m.THIS rather use just THIS does it still exist?

BTW, is there a reason you (and other people) preface memory variables with "m."? I know back in the day it was either required or suggested but it seems to cause more problems then it's worth which is nothing. In my testing there aren't any performance benefits so what's the point? Just courious.
