The output of the execution with valgrind without G_SLICE Undefined variable (same as G_SLICE set to always-malloc)

The simply program can be used to reproduce the problem.

/* The program creates a hash table and than destroy it */

int main (int argc, char * argv [])

  char * g_slice = getenv ("G_SLICE");
 
  printf ("This program creates a hash table and then destroy it\n");
  if (g_slice)
    printf ("The [G_SLICE] environment variable is set to %s\n", g_slice);
  else
    printf ("The [G_SLICE] environment variable is not set\n");
