[Bug c/37850] infinite recursive call to __mulsc3 when multiplying not-constant complexs

[mikael dot morin at tele2 dot fr]

------- Comment #6 from mikael dot morin at tele2 dot fr  2008-10-18 12:03 -------
updated testcase :
#include <complex.h>
int main ()
{
        float a = 1.;
        complex float v;
        v = I * 1.;  /* works */
        v = I * a;   /* fails */
        return 0;
}


Two conditions seem necessary for the bug to happen:
 - the testcase is compiled with -O0
 - gcc is configured and bootstrapped with CFLAGS="-O0 -g" (I suspect that -g
is unnecessary, but I don't want to test again)
