Making the variables static in addition to the functions causes the problem to
happen at -O3.
The bad behavior happens at -O3 only if g_101 is static.

To be clear: func_7() should return 1, but does not at -O2 and -Os.
In the Avrora output the result of the function looks like this:

I'm not sure what is going on, I get the same code as before using r141907 on
Ubuntu Hardy on x86. What compiler options are you using and what platform?

return left;
}
int mod_rhs (int rhs)
