Happens here too 64bit CPU 32bit builds (win or linux)

How about -O2 -ffloat-store ?

looking like a gcc optimizer bug, -O0 is fine where -O2 hangs

This only seems to affect 32-bit systems.

Check out the strace:
lstat64("/home/ubuntu/junk/p.php", {st_mode=S_IFREG|0644, st_size=59,
...}) = 0
lstat64("/home/ubuntu/junk", {st_mode=S_IFDIR|0755, st_size=4096,
...}) = 0
lstat64("/home/ubuntu", {st_mode=S_IFDIR|0755, st_size=4096, ...}) =
0
lstat64("/home", {st_mode=S_IFDIR|0755, st_size=4096, ...}) = 0
ioctl(3, SNDCTL_TMR_TIMEBASE or TCGETS, 0xbfe51238) = -1 ENOTTY
(Inappropriate ioctl for device)
fstat64(3, {st_mode=S_IFREG|0644, st_size=59, ...}) = 0
mmap2(NULL, 68, PROT_READ, MAP_PRIVATE, 3, 0) = 0xb78d1000
and then it hangs...
