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[57600] = { 0 };

and generated assembler code which the GNU-based as cannot handle:

.zerofill __DATA,__bss6,_x,230400,6
.subsections_via_symbols

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

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.

 Is there any documentation on the arguments -Wa,-q ?

-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.
