Not sure whether the testcase is valid or not. The multiplication using char
variables on both sides (and likewise for result) is: -54 * -56 (= 3024),
but (char) 3024 is -48. For int

There is no problem here at -O3. However if you make g_101 static then the
wrong answer
--- Comment #3 from regehr at cs dot utah dot edu 2009-10-03 16:44 ---
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:
r30:r31 = 0x0001
or
r30:r31 = 0x0C00

We narrowed this down to a nasty Avrora bug.
In the future we'll try to reproduce in AVR Studio before reporting.

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?

(In reply to comment #3)
The testcase is invalid, signed integer overflow is undefined behavior.
It still crashes when -fwrapv or -ftrapv is added to the command line.

Slightly simpler testcase without the silly typecasts.
int lshift_u_u (int left, int right)
{
if (right = sizeof (int) || left 4294967295U right)
return left;
}
int mod_rhs (int rhs)
{
return rhs;
}
int
