#16046: -fno-stack-protector still necessary? -------------------------------------+------------------------------------- Reporter: clumens | Owner: (none) Type: bug | Status: new Priority: normal | Milestone: Component: Build System | Version: 8.4.3 (make) | Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: None/Unknown | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Changes (by slyfox): * cc: slyfox (added) Comment: Interesting. Initially this change was added for openbsd specifically for ghc-6.5: changeset:f638fdfe1d9de1307355c8074fbff9c28342c0ef (2006) and later it was extended to cover osx: changeset:c2cd83e7d85c11e6a33e1cde263eb2312566d535 (2009) None of the reports hint at exact breakage. I guess both happened in -fvia-C mode where GHC's Evil Mangler had a chance to mangle stack canaries generated by fstack-protector. As ghc has no evil mangler anymore it could work. I'll prepare a patch. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/16046#comment:2 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
