------- Comment #1 from falk at debian dot org 2006-06-07 08:12 -------
Confirmed with 4.2.0 20060606. Cleaned up test case:
struct fann_neuron {
double value;
} __attribute__ ((packed));
void fann_run (struct fann_neuron **last_neuron) {
while (1)
(*last_neuron)->value = 1;
}
The same ICE occurs in the ufraw package, test case:
void f(double);
void SaveNikonDataFile(void) {
while (1) {
union {
double d;
unsigned char b[8];
} dat1, dat2;
dat1.d = 1;
dat2.d = 1;
dat2.b[7] = dat1.b[0];
f(dat2.d);
}
}
This one occurs only with -ffast-math.
