--- Comment #1 from Siddhesh Poyarekar <siddhesh at gcc dot gnu.org> --- recvd is uninitialized and it seems to be preventing optimization of the fortify macro one way or for some reason. I can take a look at why the condition does not get folded away but a reproducer without undefined behaviour may be more persuasive. I assume this is elfutils #29614?
