Bug#458745: arm-only miscompilation of alloca code

["Martin Guy" <martinwguy@yahoo.it>]

I just tried foo.c on up-to-date arm-sid and armel-sid systems, both
under qemu and on real hardware and I cannot reproduce the problem;
all succeed the same way, for example:

martin@qemu-armel-sid:~$ /usr/bin/gcc-4.2 foo.c
martin@qemu-armel-sid:~$ ./a.out
0xbe92ec84
0x1
0x2
0x3
martin@qemu-armel-sid:~$ gcc --version
gcc (GCC) 4.2.3 20071123 (prerelease) (Debian 4.2.2-4)

So I can only suspect a leisner problem of some kind.

If you would like to try reproducing the problem here, please get in
touch and I'll arrange access.
