The main difference between the original test case and the reduced one is the
type of test expression. I think in the fix you need to treat the address type
similar to an unsigned integer.

I reduced the test to:

extern void abort (void);
__attribute__ ((noinline)) int
foo (int *zzz, unsigned int kk)
{
int a, b, d;
a = b = 0;
for (d = 0; d 1000; d

The optimization performed is correct because:
In C++ (not in C) a const modifier in a global variable has internal
linkage (i.e. it is treated like a static variable) and therefore the
optimization performed

We used -O2 -fsched-pressure -fschedule-insns to build the cpu2006 bmks on an
amd64-linux machine.
Thanks for the list of bugs.

Confirmed. Also note -fschedule-insns is basically broken for x86 anyways.
Do you have a list of bug reports where -fschedule-insns is broken on x86?
We tried to compile all the SPEC 2006 with this option
