There is no need for fix a error as there are no error. The 'fd' is correctly initialized with no exception, althought GCC can't evaluate it. It's try to eliminate unnecesarry warning. > No. I don't know why you think that this is a good fix for all the > uninitialized pointer warnings. It's not. Never :-/ Why ? It's written within the "description" section of the PR. Warning shoult be "attention marks" - THIS CONSTRUCT SHOULD BE REVIEWED. If there are too many warnings related to correct code we can't use it for it purpose. Warnings become notice with almost no value. Well. I compiled the code and evaluate that hundreds of warnings didn't point to problematic code, but are "false" only. I will compile the code next month. Do you think I recognise there are hundreds + 1 warning, so we should evaulate this +1 warning to be sure there are no error ? Warnings may be very usefull information, unless they lie so much. Current code cause piles of false warnings. It "warnings" are hard to use as true warning ... But any commiter can close all of my PR if he think I'm not true ... > After a quick glance at the source of rpcbind() I think that there's no way > that my_xrpt can be used uninitialized.

The unnecesarry initialisation of variable initialised again later seems to be vaste of resources. But IMHO only.
