The C++ parser fails to parse sizeof compound-literal correctly. For example,
int x = sizeof (int) { 1 };
receives the error
t.C:1: error: expected %,% or %;% before '{' token
As shown in the grammar for GNU extensions in comments in cp/parser.c,
compound literals are considered

I think this is related to PR 17919 (or is a dup of that bug). I think this is GC
related.

Produces wrong code on both 3.3.4 and 3.4.2 (in Debian Sid). It works perfectly
with gcc 2.95.
The problem is that,
-A+B == B-A
-A()+B == B-A()
-A+B() == B()-A
but,
-A()+B() ?= B()-A()
if A or B depend on each other, the last condition is !=. Otherwise, it is ==.
This breaks any code that relies

Invalid:
printf( -4.0 is %f\n, -A() + A());
either A() can be evaluated first which is the misunderstanding in your part.

I doubt this code is valid, but anyway, GCC should display a proper
error message rather than just crash.
I am using a GCC checked out from CVS HEAD yesterday.
I also get an ICE with GCC 3.3.4-11 and 3.4.1-17 from Debian,
but i haven't tried the corresponding FSF releases.

This problem appears to be a confluence of issues between fix_truncdfdi2 and
limitations of reload, exacerbated by Apple's LL64 mode.
The problematic code is

GCC is now more consistent about when this bug triggers, so some cases which passed in
3.4 fail in
4.0.
There are testcases for this bug, gcc.dg/c90-const-expr-3.c and
gcc.dg/c99-const-expr-3.c.

tracked it down in HEAD but the same patch causes a similar problem in the 3.4
