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

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

Using built-in specs.

How reproducible:

Steps to Reproduce:
1. Compile the source file with gcc-4.6.1 -Wall test.c -o test

Actual results:

test.c: In function 'main':
test.c:21:1: internal compiler error: in elimination_costs_in_insn, at
reload1.c:3633

Expected results:

With malloc:

Valor: 0.671913
Valor: 0.580317
Valor: 0.235468
Valor: 0.285724
Valor: 0.198874
Valor: 0.445921
Valor: 0.102851
Valor: 0.881226
Valor: 0.080384
Valor: 0.988736
La posicion 5 tiene el valor: 3.115597e-01

With gcc4.1: Segmentation Fault (Logically this result is espected)

Additional info:


I'm running a Gentoo:

Linux version 2.6.39-gentoo-r3 (root@gentoo) (gcc version 4.4.5 (Gentoo 4.4.5

I became a similar error reported to redhat with gcc 4.4 Bug 730382
