#10320: -ddump-to-file should create empty dump files when there was nothing to dump -------------------------------------+------------------------------------- Reporter: rwbarton | Owner: tvv Type: bug | Status: patch Priority: low | Milestone: Component: Compiler | Version: 7.10.1 Resolution: | Keywords: newcomer Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: None/Unknown | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Phab:D1514 Wiki Page: | -------------------------------------+------------------------------------- Comment (by osa1): This patch breaks things; try `-ddump-to-file -ddump-simpl`, it's failing with: {{{ Main.dump-simpl: hPutStr: illegal operation (handle is closed) }}} I had to comment out `bracket_`s first argument that closes handles. It seems like it's closing handles too soon. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/10320#comment:7 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
