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.

How reproducible:

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

            (clobber (mem/c:SI (plus:DI (reg/f:DI 20 frame)
