#8852: 7.8.1 uses a lot of memory when compiling attoparsec programs using <|> -------------------------------------+------------------------------------- Reporter: joelteon | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 7.8.1-rc2 Resolution: | 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: | -------------------------------------+------------------------------------- Comment (by simonpj): This is the dreaded `SpecConstr` blowup again (see #8980, #8941 (possibly), #8960, #7898, #7068, #7944, #5550, #8836). Compiling with `-fno-spec-constr` makes it go through fine, so that's a workaround.
