Hello folks,
I compiled the valgrind and memcheck for powerpc and it went through fine.
However I see that leak is not getting detected.
Compiled the below program with -O0 -g flags
[mv_mm-dev valgrind-3.12.0 (IAP-MASTERSON)]$ cat valg.c
#include <stdlib.h>
void f(void)
{
int* x = malloc(10 * sizeof(int));
printf("hello \n");
//x[10] = 0; // problem 1: heap block overrun
} // problem 2: memory leak -- x not freed
int main(void)
{
f();
return 0;
}
