#14741: High-memory usage during compilation using Template Haskell -------------------------------------+------------------------------------- Reporter: donatello | Owner: sighingnow Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 8.2.2 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: Type of failure: Compile-time | Unknown/Multiple performance bug | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Phab:D4384 Wiki Page: | -------------------------------------+------------------------------------- Comment (by sighingnow): Embedding ~100MB static data in haskell code may consume around 40GB memory. Currently in TH the `StringPrimL` is built with `[Word8]` rather than ByteString. Unpacking ~100MB bytestring to `[Word8]` and escaping it already consume GBs of memory. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/14741#comment:13 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
