It's indeed not a regression.

Here is at least a testcase for the MAX_EXPR problem:
Compile with -O0, works, compiling with -O2 -fno-tree-lrs does not.
long fff[10];
long f(long a, long b)
{
long crcc = b;
long d = *((int*)(a+1));

The program is correct, because you are still accessing a MGS object through a
MGS pointer, so GCC should not segfault here.

Andrew, your testcase is invalid. You cannot access a variable of long type
through a pointer to int. I know the original code disables strict aliasing,
but I did not test if your testcase also aborts with

This is a FIXME that I need to free a constraint letter (probably the existing
R) as a constraint for (MEM reg), or more to the point, a side-effect-free
memory constraint: the libstdc++ asms are buggy and could get autoincrement.
Actually, there should be a generic constraint letter for that:

Followin patch fixes the alignment problem. But it cannot be applied because it
breaks ABI
compatibilty.
A possible solution is to relax alignment of the type in question (with
alignment of 128) to that of

Obvious patch posted here:

This is not a wrong-code bug. At worst it will crash the compiler,
but probably it just works by luck, because of

And this is the patch that I had in mind. Can this break ABI compatibily? My
limited testing shows
that it does not.

I could reproduce it with 20041208 but with 20041214 it is fixed, can you test
a newer GCC?
Latest CVS works fine.
Ticket can close.

Here is the current results for 3.3.2 vs the mainline:
Now I am getting results that -O3 is faster than -O2, that is not right.

Indeed a Heisenbug:
Does anyone know how I could disassemble those .o files to get something
more

Use otool.
