This is very strange. I was using SIntInstall this last weekend. It was
failing. I set TMON to trap on _SIntInstall, and found that it appeared
to have garbage in the registers. So I single stepped through the glue
code, and found that it takes the arguments in the wrong order.
Now for the strange part: I was using LightspeedC, not MPW!
I was using 2.11, with a copy of SlotMgr.h from god only knows
where. I haven't yet tried it with 2.13 and the 2.15 libraries
( mainly because it just occured to me that that might make a
difference ).

The 2.11 Mactraps copies the argument reversal bug from the MPW interfaces. It is corrected in 2.15. (If memory serves, this is one of the few differences between the 2.13 and 2.15 Mactraps.) -- Michael Kahl, Symantec
