#14637: Simplifier Ticks Exhausted when compiling with profiling -------------------------------------+------------------------------------- Reporter: cfhammill | Owner: (none) Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 8.2.2 Resolution: | Keywords: Operating System: Linux | Architecture: x86_64 Type of failure: Compile-time | (amd64) crash or panic | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by sighingnow): Compile with `inplace/bin/ghc-stage2 --make bug2.hs -prof -fprof-auto-top -fforce-recomp -O -fno-s trictness -fno-specialise -fno-do-lambda-eta-expansion` then the error disappears. From trace the most of `tick` calls come from `simplLam` in simplCore/Simplify.hs, {{{ simplLam env (bndr:bndrs) body (ApplyToTy { sc_arg_ty = arg_ty, sc_cont = cont }) = do { tick (BetaReduction bndr) ; simplLam (extendTvSubst env bndr arg_ty) bndrs body cont } }}} -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/14637#comment:10 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
