#7737: t7319: Oops! Entered absent arg w_s1Du{v} [lid] [base:GHC.Base.String{tc 36u}] -----------------------------+---------------------------------------------- Reporter: luite | Owner: Type: bug | Status: new Priority: normal | Component: Compiler Version: 7.7 | Keywords: Os: Unknown/Multiple | Architecture: Unknown/Multiple Failure: None/Unknown | Blockedby: Blocking: | Related: -----------------------------+---------------------------------------------- When compiling t7319 from the test suite with -O2, I get the above error, tested with latest HEAD (20130304). Reporting since this looks weird, and t7319 is not compiled with this option in the suite (it's a test for stack traces, i found it while debugging GHCJS which has its own test suite runner but borrows tests from GHC) {{{ luite@wolfgang:~/buildtest/ghcjs/test/ghc/codeGen$ ghc -O2 -fforce-recomp t7319.hs [1 of 1] Compiling Main ( t7319.hs, t7319.o ) Linking t7319 ... luite@wolfgang:~/buildtest/ghcjs/test/ghc/codeGen$ ./t7319 t7319: Oops!
