#14788: `error` in GHC internals can disappear by rerunning ghc again -------------------------------------+------------------------------------- Reporter: nh2 | Owner: (none) Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 8.2.2 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: Type of failure: Poor/confusing | Unknown/Multiple error message | Test Case: Blocked By: | Blocking: Related Tickets: #14533 | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by simonpj):
I suggest that ghc either deepseq the string to be written to the .o file before calling writeFile or equivalent,
That imposes a cost on every compilation. Maybe instead remove any `.o` file if a panic occurs? That would impose costs only on the panic path. This would entail noting what files are "in flight", so that the exception handler can delete them. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/14788#comment:1 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
