Bug in osMailCAlloc (cmsis_os.c)

I believe there is a bug in the osMailCAlloc function from cmsis_os.c V1.02 (STM32Cube_FW_F1_V1.4.0).

The function will always assign 0 to the first 4 bytes of the block, since sizeof an uint32_t is 4.

if (p) {

  for (i = 0; i < sizeof(queue_id->queue_def->item_sz); i++) {

    ((uint8_t *)p)[i] = 0;

  }

}
