[GHC] #15917: GHC seems to re-read source of module to produce fancy error msgs
#15917: GHC seems to re-read source of module to produce fancy error msgs -------------------------------------+------------------------------------- Reporter: Heimdell | Owner: (none) Type: bug | Status: new Priority: lowest | Milestone: 8.6.3 Component: Compiler | Version: 8.2.2 Keywords: re-reading | Operating System: Unknown/Multiple Architecture: x86_64 | Type of failure: Poor/confusing (amd64) | error message Test Case: | Blocked By: Blocking: | Related Tickets: Differential Rev(s): | Wiki Page: -------------------------------------+------------------------------------- I had a module with unused name `txFees` in it. I started compilation and in the same time edited code by renaming `txFees` -> `_txFees`. I got the following message: {{{ warning: [-Wunused-matches] Defined but not used: ‘txFees’ | 40 | } _txFees | ^^^^^^ <no location info>: error: Failing due to -Werror. }}} The screenshot is in the attachment. Notice that message part is about old code (`txFees`), and preview is about new code (`_txFees`). -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/15917 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
