>Release: FreeBSD 2.1.0-RELEASE i386
>Environment:
Pentium 100 MHz, 256 Kb Pipeline burst cache, 430FX Chipset, 16 Mb ram.
gcc version 2.6.3
>Description:
Compilation of the program below with gcc -O yields:
"gcc: Internal compiler error: program cc1 got fatal signal 10"
The same error message appears when trying with -O2, but not with
-O3 or -O4.
>How-To-Repeat:
Compilation of the program below with gcc -O will repeat the error
struct s1 { double x, y, z; };
struct s2 { double r, g, b; };
struct s3 {
struct s1 p;
struct s2 c;
};
void create_light(struct s3 *li,
double x, double y, double z,
double r, double g, double b)
{
li->p.x = x;
li->p.y = y;
li->p.z = z;
li->c.r = r;
li->c.g = g;
li->c.b = b;
}
>Fix:
Work-around: declare "li" volatile.
