gcc 3.1 hangs forever on Red Hat 7.2 system

[Reichelt]

Hi,

the bug also appears on mips-sgi-irix6.5.
It's a regression from gcc 3.0.x.

Bye the way, one can reduce the example a little more:

void f(void)
{
    int c;
    if (c)
        return;
    if (c)
        while (1)
            f();
}

Greetings,
Volker Reichelt
