#5728: Warnings from -fwarn-incomplete-record-updates even with all constructors matched -------------------------------------+------------------------------------- Reporter: mjo | Owner: Type: bug | Status: new Priority: normal | Milestone: ⊥ Component: Compiler | Version: 7.4.1 Resolution: | Keywords: warnings Operating System: | Architecture: Unknown/Multiple Unknown/Multiple | Difficulty: Unknown Type of failure: Incorrect | Blocked By: warning at compile-time | Related Tickets: Test Case: | Blocking: | Differential Revisions: | -------------------------------------+------------------------------------- Changes (by simonpj): * cc: george.karachalias@…, tom.schrijvers@… (added) Comment: Actually not. The warning was being suppressed by {{{ handleWarnings = if isGenerated origin then discardWarningsDs else id }}} in `matchWrapper`, which is really intended to suppress warnings in code generate by `deriving` etc. I've fixed this which makes the warning come back. It's really is part of the pattern-match-fixup problem. Fortunately, Geroge K and Tom S are working on this.
