-// Our goal is to emulate an instrumented allocator, whose calloc
-// invoked from dlsym will trigger shadow faults, to test an
-// early shadow fault during esan interceptor init.
-// We do this by replacing calloc:
-void *calloc(size_t size, size_t n) {
-  // Unfortunately we can't print anything to make the test
-  // ensure we got here b/c the sanitizer interceptors can't
-  // handle that during interceptor init.
-
-  // Ensure we trigger a shadow write fault:
-  int x[16];
-  x[0] = size;
-  // Now just emulate calloc.
-  void *res = malloc(size*n);
-  memset(res, 0, size*n);
-  return res;
