#7411: Exceptions are optimized away in certain situations -------------------------------------+------------------------------------- Reporter: SimonHengel | Owner: tdammers Type: bug | Status: new Priority: high | Milestone: 8.8.1 Component: Compiler | Version: 7.6.1 Resolution: | Keywords: seq, deepseq, | evaluate, exceptions Operating System: Linux | Architecture: x86_64 | (amd64) Type of failure: Incorrect result | Test Case: at runtime | simplCore/should_fail/T7411 Blocked By: | Blocking: Related Tickets: #5129 #15225 | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by tdammers): Oh dear. It turns out my bash script that I used to automatically build the required GHC's and run nofib had a bug that caused it to silently ignore mistyped build flavours, so instead of "GHC compiled with -fno- state-hack", I got "GHC compiled with the default flavour". Which explains the whopping difference: where I thought I was comparing "GHC compiled with -prof -fno-state-hack vs. GHC compiled with -prof", I was actually comparing "GHC release build vs. GHC prof build". Fortunately, the nofib flags were correct, so the part about the effect of `-fno-state-hack` on the nofib suite remains valid. I'll re-run the tests for "GHC compiled with -fno-state-hack", and I'll also throw in "Boot libraries compiled with -fno-state-hack, GHC compiled normally". -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/7411#comment:48 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
