#10171: runghc has problem when the argument list is too big -------------------------------------+------------------------------------- Reporter: redneb | Owner: Type: bug | Status: new Priority: low | Milestone: Component: Compiler | Version: 7.11 Resolution: | Keywords: Operating System: POSIX | Architecture: Type of failure: Runtime crash | Unknown/Multiple Blocked By: | Test Case: Related Tickets: | Blocking: | Differential Revisions: -------------------------------------+------------------------------------- Comment (by redneb): Currently, when you run `runhaskell script.hs arg1 arg2`, `ghc` is called with the following arguments: {{{ -ignore-dot-ghci -x hs -e ':set prog "script.hs"' -e ':main ["arg1", "arg2"]' }}} Note the the `["arg1", "arg2"]` part is generated by calling `show` on the list of original arguments. This is very inefficient. One solution is to introduce a new flag for `ghc` that would directly interpret the specified file. The new flag must have a short name so that the length of `"ghc"` plus the length of the flag name plus 1 (for the null character) is less than the length of `"runhaskell"`. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/10171#comment:1 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
