Program terminated with signal SIGABRT, Aborted

[imxys]

I'm using node-dbus on platform Hi3559. I tried DBus 1.13.7 and 1.10.26. Node version is 8.15.0 . Error info lists below:

Core was generated by `node app.js'.

Seems the code calls dbus_free() to free memory alloced by strdup() .

caller code:

  // src/signal.cc  Line 83
  // Create a signal
  char* path = strdup(*String::Utf8Value(
      v8::Isolate::GetCurrent(),
      info[1]->ToString(Nan::GetCurrentContext()).ToLocalChecked()));

  // Line 130
  dbus_free(path);

dbus code:

/**
 * Frees a block of memory previously allocated by dbus_malloc() or
 * dbus_malloc0(). If passed #NULL, does nothing.
 * 
 * @param memory block to be freed
 */
void
dbus_free (void  *memory)
{
#ifdef DBUS_ENABLE_EMBEDDED_TESTS
  if (guards)
    {
      check_guards (memory, TRUE);
      if (memory)
        {
#ifdef DBUS_DISABLE_ASSERT
          _dbus_atomic_dec (&n_blocks_outstanding);
#else
          dbus_int32_t old_value;

          old_value = _dbus_atomic_dec (&n_blocks_outstanding);
          _dbus_assert (old_value >= 1);
#endif

          free (((unsigned char*)memory) - GUARD_START_OFFSET);
        }
      
      return;
    }
#endif
    
  if (memory) /* we guarantee it's safe to free (NULL) */
    {
#ifdef DBUS_ENABLE_EMBEDDED_TESTS
#ifdef DBUS_DISABLE_ASSERT
      _dbus_atomic_dec (&n_blocks_outstanding);
#else
      dbus_int32_t old_value;

      old_value = _dbus_atomic_dec (&n_blocks_outstanding);
      _dbus_assert (old_value >= 1);  // dbus-memory.c: Line 734
#endif
#endif

      free (memory);
    }
}

I replace dbus_free() with free() and it works.
