Produces incorrect slices given the following source code (line numbers included for clarity):
1 void bar(int a, int b) {
2 if (a != 0) return;
3 if (b == 42) return;
4 printf("%d %d\n", a, b);
5 }

7 int foo(int x) {
8 int v = 0;
9 for (int i = 0; i < x; ++i) {
10 v++;
11 }
12 bar(x, v);
13 return 0;
14 }

16 int main() {
17 int n = 3;
18 return foo(n);

Is this the expected output? If not, is this resolved when building most recent version from source?
Produces incorrect slices given the following source code (line numbers included for clarity):
Produces the following srcSlice output:
In the first line of the srcSlice output,
nis correctly defined and used. However, I also expected n to appear incfuncs{foo(1)}. Additionally, variablevis incorrectly stated to be used on lines 2 & 4 which appears to actually be where variablexshould be used.Is this the expected output? If not, is this resolved when building most recent version from source?
To be clear, I downloaded prebuilt srcML from https://www.srcml.org/#download and prebuilt srcSlice from https://www.srcml.org/tools.html
To produce the above, I used the following commands:
$ srcml example.cpp --position -o example.xml $ srcslice example.xml > example.slice $ cat -n example.slice
