Bug #: 50092
Summary: internal compiler error: in elimination_costs_in_insn,
at reload1.c:3633
Classification: Unclassified
Product: gcc
Version: 4.6.1
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c
AssignedTo: unassigned@gcc.gnu.org
ReportedBy: mario.trangoni@intel.com

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.

Thread model: posix
gcc version 4.6.1 (Gentoo 4.6.1 p1.0, pie-0.4.5)
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
Please submit a full bug report,
with preprocessed source if appropriate.
See <http://bugs.gentoo.org/> for instructions.
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
p1.2, pie-0.4.5) ) #4 SMP Tue Jul 19 01:03:04 Local time zone must be set--see

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

Confirmed. Reduced testcase:
int main(int argc, char **argv)
{
int i;
_Complex long double vector[100000000];
for (i=0 ; i<10 ; i++)
printf("Valor: %Lf\n", (long double) rand()/ 2147483648.0);
printf ("La posicion 5 tiene el valor: %Le\n", (long double) vector[5]);
}
ICEs in various ways depending on optimization level. With -m32 the
array is diagnosed as being too large. At -O1:
t.3.i: In function 'main':
t.3.i:6:5: warning: incompatible implicit declaration of built-in function

4.3 is happy with the code.
