In the following code, in the loop at line 381 of jtagmkII.c (line 2586 of the
attached jtagmkII.i), msglen (and l, as I recall) contain incorrect values.
This only happens when optimization is turned on (-O2); it does not happen with
-O1. The code runs correctly when compiled with gcc-3.3 using optimization.

------- Comment #2 from rguenth at gcc dot gnu dot org 2006-04-05 14:26 -------
It's hard to verify with this big (non-executable) testcase. Is there a chance
you can strengthen your claim?

Can you try 4.0.3? Otherwise just report this to Apple instead as you are
using Apple's hacked up Compiler.

Tried 4.0.3 (compiled from source via Darwinports); works OK there.
