#11195: New pattern-match check can be non-performant -------------------------------------+------------------------------------- Reporter: goldfire | Owner: Type: bug | Status: new Priority: highest | Milestone: 8.2.1 Component: Compiler | Version: 7.11 Resolution: | Keywords: | PatternMatchWarnings Operating System: Unknown/Multiple | Architecture: Type of failure: Compile-time | Unknown/Multiple crash | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Phab:D1676, Wiki Page: | Phab:D1795 -------------------------------------+------------------------------------- Changes (by simonpj): * status: closed => new * resolution: fixed => Comment: I'm re-opening this because compilation still takes a ridiculously long time (minutes) and memory (6.7G allocated). Almost all of this is in the pattern-match checking. It can't be right!
