This sounds like a bug in Apple's assembler.

This gives the same errors within MacOS 10.8 and 10.9

I think it is: 'as' fails if the bit 32 of the length in '.zerofill' is 1 (bits
above 32 can be set as long as bit 32 is 0).
Workaround: use the Clang 'as', i.e., compile with -Wa,-q.
Note '.zerofill' appeared between r167173 (no zerofill) and r167380 (zerofill).
Note that the code works on darwin10.
This PR should probably closed as INVALID.

zerofill has been introduced at r167242 and AFACT is darwin specific.

--- Comment #6 from Barry McInnes <barry.j.mcinnes at noaa dot gov> ---
Is there any documentation on the arguments -Wa,-q ?
With a link from Macports to /usr/bin/clang one program works without -Wa,-q,
but others still need those parameters to get rid of the zero fill error.

-Wa,* is documented somewhere in the manual as the way to tell the assembler to
use the option *. AFAIR 'as -q' is documented (otherwise I won't have guessed
it), but I don't have a pointer.
Note that another workaround is to make the array allocatable.

--- Comment #8 from Francois-Xavier Coudert <fxcoudert at gcc dot gnu.org> ---
The assembler issue was submitted to Apple as bug #18860674. I don't have high
hopes, but I don't think there's much more we can do.
For completude: one-line C testcase that triggers the same issue:
static int x[576000000] = { 0 };
and generated assembler code which the GNU-based as cannot handle:
.zerofill __DATA,__bss6,_x,2304000000,6
.subsections_via_symbols
