#4241: Optimization causes HUnit to behave incorrectly
---------------------------+------------------------------------------------
Reporter: beej175560 | Owner:
Type: bug | Status: new
Priority: normal | Component: Compiler
Version: 6.12.1 | Keywords:
Testcase: | Blockedby:
Os: MacOS X | Blocking:
Architecture: x86 | Failure: Incorrect result at runtime
---------------------------+------------------------------------------------
When I build the following program with "ghc -O2 --make ...", the unit
test passes. I expect the test to fail because 1 does not equal 2.
Compiling without optimization results in correct behavior.
I'm not sure if this is a compiler bug but I'm filing it as such because
of the dependence on optimization. I'm running ghc on Mac OS 10.6.3
installed from the downloaded file haskell-platform-2010.1.0.1-i386.dmg.
The ghc version is 6.12.1.
import Test.HUnit
tests = test [ test [1 ~?= 2] ]
main = runTestTT tests
