--- Comment #4 from Peter Selinger <selinger at mathstat dot dal.ca> ---
I ran into the same bug with this code:
double weight() {
double sum;
int i;
for (i=0; i<10; i++) {
sum++;
}
return sum;
}
With -Wuninitialized or -Wmaybe-uninitialized, no warning is generated with
-O0. The warning is generated with -O1, -O2, -O3. Other compilers (such as
clang) generate the warning correctly.
Confirmed with gcc 8.2.0.
