[Bug rtl-optimization/27044] New: Loop variables incorrectly initialized with optimization on

[ned at bike-nomad dot com]

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.
