Description of problem:
Error declaring a big vector by value of datatype complex long double.
I'm using the library complex.h
If I do the same with malloc there's no problem.

Version-Release number of selected component (if applicable):

Using built-in specs.

How reproducible:

Steps to Reproduce:
1. Compile the source file with gcc44 -Wall test.c -o test
  
Actual results:

test.c: In function ‘main’:
test.c:21: error: unrecognizable insn:
(insn 74 20 22 3 test.c:16 (parallel [
            (set (reg:XF 68 [ D.2997 ])
                (float:XF (reg:SI 69 [ D.2996 ])))
            (clobber (mem/c:SI (plus:DI (reg/f:DI 20 frame)
                        (const_int -32000000036 [0xfffffff88ca6bfdc])) [0 S4 A32]))
        ]) -1 (expr_list:REG_DEAD (reg:SI 69 [ D.2996 ])
        (nil)))
