Hi all,
Valgrind identifies uninitialized memory when it's used in a
conditional. It's very smart and can tell when one uninitialized value
is assigned to another. I'd like to be able to see is a trace of all of
those assignments that lead to the report starting from the reported
conditional. Can I?
In the following code for instance valgrind reports line 16. But could
it report lines 7,14,15 as well? That would be very useful! In real life
the flagged if statement can be far removed from the initial source of
the bug!
1 #include<iostream>
2 using std::cerr;
3 using std::endl;
4
5 int fun(int d)
6 {
7 return d+1;
8 }
9
10 int main(int argc, char **argv)
11 {
12 int r,q,j;
13
14 q=j;
15 r=fun(q);
16 if (r) { ++k; }
17 cerr << k << endl;
18
19 return 0;
20 }
