That's really odd, and I can't imagine why that happens.  There's a global
variable called return_true_variant.  If it's 0, then invoke() will try
to convert the variant (pointer) to a real value via get_variant().

What happens at the end of invoke?  The only thing I can think of is that
for some reason, the variant was set up as a VT_I4 rather than a 
VT_BSTR (even though it's really a pointer to the string).  If that's
what's going on, then it sounds like something happening on the ADO side
of things.  Either way, I have no clue why tracing would make any 
difference.
