#8116: Segfault/panic of 32bit GHCi on Mac ----------------------------------+------------------------------------ Reporter: kazu-yamamoto | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 7.6.3 Resolution: | Keywords: Operating System: MacOS X | Architecture: Unknown/Multiple Type of failure: GHCi crash | Difficulty: Unknown Test Case: | Blocked By: Blocking: | Related Tickets: ----------------------------------+------------------------------------ Comment (by shelarcy): Second bug is caused by DYNAMIC_GHC_PROGRAMS on Mac OS X platform. I reproduced that on 64 bit GHCi, if DYNAMIC_GHC_PROGRAMS = Yes when building GHC HEAD. {{{ $ ghc --info [("Project name","The Glorious Glasgow Haskell Compilation System") (snip) ,("Project version","7.7.20130810") ,("Booter version","7.6.3") ,("Stage","2") ,("Build platform","x86_64-apple-darwin") ,("Host platform","x86_64-apple-darwin") ,("Target platform","x86_64-apple-darwin") (snip) ,("Support dynamic-too","YES") ,("Dynamic by default","NO") ,("GHC Dynamic","YES") ,("Leading underscore","YES") ,("Debug on","False") ,("LibDir","/Library/Frameworks/GHC.framework/Versions/7.7.20130810-x86_64/usr/lib/ghc-7.7.20130810") ,("Global Package DB","/Library/Frameworks/GHC.framework/Versions/7.7.20130810-x86_64/usr/lib/ghc-7.7.20130810/package.conf.d") ] }}} {{{ Prelude Data.Complex> ((-2) :+ 0)**(1.5 :+ 0) ghc: panic!
