  Sorry. I never even noticed that you had attached the example code.
Mumble. Mumble.

  As an act of contrition I tried your code and it seems to work OK for
me.  I am not using the latest SNC but instead have 1.9B3. I had a quick
scan of the diffs between it and 1.9.1 and don't see anything
significant but it would be easy to miss something small.

  There _was_ a problem with the "+r" option where the block of memory
for the variables was never being allocated. The result was that the
variables for all instances were accessed relative to zero rather than
relative to the allocated base address. This would give the behavior
that you observe but would also quite likely give segmentation faults
and other weird behavior. One test would be to print the value of the
pVar pointer in a bit of escaped C code and check that it is (a) not
zero and (b) different in each instantiation. If it isn't, that is a big
clue.

  Hope this really helps this time,

  William
