The input raw profile test has been generated from the following source code:
|
|
|
|
```
|
|
#include <sanitizer/memprof_interface.h>
|
|
#include <stdlib.h>
|
|
#include <string.h>
|
|
int main(int argc, char **argv) {
|
|
char *x = (char *)malloc(10);
|
|
memset(x, 0, 10);
|
|
free(x);
|
|
__memprof_profile_dump();
|
|
x = (char *)malloc(10);
|
|
memset(x, 0, 10);
|
|
free(x);
|
|
return 0;
|
|
}
|
|
```
|
|
|
|
The following commands were used to compile the source to a memprof instrumented
|
|
executable and collect a raw binary format profile. Since the profile contains
|
|
virtual addresses for the callstack, we do not expect the raw binary profile to
|
|
be deterministic. The summary should be deterministic apart from changes to
|
|
the shared libraries linked in which could change the number of segments
|
|
recorded.

We expect 2 MIB entries, 1 each for the malloc calls in the program.
