I'm working here on a Linux laptop:
I am geting a seg fault. Its fine when the second call is commented out.
I am not sure if any of the following is any use to you.
The follwoing PASM was part generated from your IMC, I added the bits
between ###. This calls the sub twice I am not sure if it is any use
to you. Please see some output from GDB at the end.
_main:
set P16, P1
newsub P16, 45, _dummy
@pcc_sub_call_2:
set I5, 1
set P0, P16
set I0, 1
set I1, 0
set I2, 0
set I3, 0
savetop

restoretop

set I5, 2
set I0, 1
set I1, 0
set I2, 0
set I3, 0
savetop

end
_dummy:
print dummy was called with:
print I5
print \n
