This is a known problem: GCC internally represents the size of an
array as the number of bits, instead of the number of bytes; so that
range overflows unsigned 32bit. You either need to make the array
slightly smaller, or use a 64-bit-machine.

This is the GCC list :-)

Depends on the release, the front-end, and the target architecture. In
the mainline compiler, I believe the C compiler does not have the
problem anymore.
