If I read the standard correctly, restrict makes an assumption about the dynamic extent of an executed block. This seems obvious from section 6.7.3.1 (of ISO C18) which speaks of the block of main in paragraph 2 and the lifetime of objects in paragraph 5. ^ permalink raw reply [flat|nested] 4+ messages in thread
