#8852: 7.8.1 uses a lot of memory when compiling attoparsec programs using <|> -------------------------------------+------------------------------------- Reporter: joelteon | Owner: Type: bug | Status: closed Priority: normal | Milestone: Component: Compiler | Version: 7.8.1-rc2 Resolution: fixed | Keywords: Operating System: | Architecture: Unknown/Multiple Unknown/Multiple | Difficulty: Unknown Type of failure: Compile- | Blocked By: time performance bug | Related Tickets: Test Case: | Blocking: | Differential Revisions: | -------------------------------------+------------------------------------- Changes (by simonpj): * status: new => closed * resolution: => fixed Comment: OK I have finally fixed this bug. I think there is a good chance that doing so has also fixed #8852, #8980, #8941 (possibly), #8960, #7898, #7068, #7944, #8836. I have turned these tickets into info-needed status, because they are hard to reproduce, but this ticked #8852 is definitely fine now. It's kind of hard to make a regression test without depending on an (out of date version of) attoparsec, and its dependencies, so I'm not adding a regression test at all for now.
