Hi,

> Roman, you don't mention how you compile the file. What compiler options are you using? Is this an optimization bug, or maybe a target-specific bug?
It's an optimization bug. It's enough to compile this file with -O2, a
cross compiler shows the same result.
I can only reproduce the problem for m68k, although I think it's not
target specific.
