If malloc fails in __command_name, the following strcpy will segfault, thus preventing __command_name to return. The actual calls to command_name() implement the correct check for the NULL pointer, but propagate error -ENOMEM, that is not an error value coherent within OpenOCD. Plus, in one case it overwrites an already detected error. Check the pointer returned by malloc and, in case of failure, issue an error message and return the NULL pointer. Let the caller of command_name() to keep the already detected error or to return ERROR_FAIL in case of end of memory.
