#4012: Compilation results are not deterministic -------------------------------------+------------------------------------- Reporter: kili | Owner: Fuuzetsu Type: bug | Status: new Priority: high | Milestone: 7.12.1 Component: Compiler | Version: 6.12.2 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: Type of failure: Other | Unknown/Multiple Blocked By: | Test Case: Related Tickets: | Blocking: | Differential Revisions: -------------------------------------+------------------------------------- Changes (by simonpj): * priority: normal => high Comment: George Colpitts asks: the milestone is 7.12.1, should it be 7.10.2? It would be unusual to delay a patch-level release for a ticket that has been open for five years. Doing so would mean indefinitely delaying 7.10.2. By “indefinite” I don't mean "forever", I just mean “we don’t know how long”: * We don’t have anyone owning the ticket, * we don’t know how difficult it is to fix; and * a full bulletproof fix is probably quite challenging (e.g. forcing the unique-supply generator to give reproducible results even though some (ultimately irrelevant) bits of the environment have changes, would be difficult) At the same time we have some folk urging us to get 7.10.2 out sooner rather than later. So everyone: * If you think we should delay 7.10.2 pending at least some progress on this, please say so on the ticket. * Better still, roll up your sleeves and take a crack at understanding more precisely what is going on, and proposing a fix.
