Description:
mtrace() suppose to use MALLOC_TRACE environment variable to open the trace file and add trace about head memory usage. but its not happening. I also added '#define _GNU_SOURCE' at the beginning, not working

example test.c:

#define _GNU_SOURCE
#include <mcheck.h>

int main(int argc, char *argv[]) {
char *buffer = NULL;
buffer = calloc(1, 1000);
free(buffer);
return 0;
}

compile:
$ gcc -o test test.c

command which I used to run the test:
$ (export MALLOC_TRACE=$(pwd)/test.mtrace; ./test)
