bug linear loop transforms

[Alex Turjan]

Im writing to you regarding a possible bug in linear loop transfor.
The bug can be reproduce by compiling the attached c file with gcc.4.5.0 (20100204, 20100325) on x86 machine.

The compiler flags that reproduce the error are:
-O2 -fno-inline -fno-tree-ch -ftree-loop-linear

If the compiler is run with:
-O2 -fno-inline -fno-tree-ch -fno-tree-loop-linear 
then the produced code is correct.
