Bug ID: 60791
Summary: missing warning about uninitialized local variable
Product: gcc
Version: 4.8.2
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c
Assignee: unassigned at gcc dot gnu.org
Reporter: dominik.muth at gmx dot de
// When compiling this file with
//
// -O3 -Wall -c
//
// There is no warning about the uninitialized use of r.
int f(int i) {
int r;
while (r != 0) {
r = 0;
i++;
}
return i;
}
// This is true for 4.6.3 and 4.8.2. However 2.95.2 does issue the warning.
//
// Leaving out optimization none of the above mentioned versions produces the
// warning (similar to 54554).
