#8798: Missing symbols with -fprof-auto-calls ------------------------------------+------------------------------------- Reporter: edsko | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 7.6.3 Keywords: | Operating System: Unknown/Multiple Architecture: Unknown/Multiple | Type of failure: None/Unknown Difficulty: Unknown | Test Case: Blocked By: | Blocking: Related Tickets: | ------------------------------------+------------------------------------- To reproduce: in an empty environment (no packages installed), run {{{ cabal install --only-dependencies --enable-library-profiling --ghc-option =-fprof-auto-calls }}} for the attached test case. This will seem to work okay (no errors), but if you then do {{{ cabal configure --enable-executable-profiling --enable-library-profiling --ghc-option=-fprof-auto-calls }}} then {{{ cabal build }}} will fail with {{{ Building autocallsbug-0.1.0.0...
