#10712: Regression: make TEST=exceptionsrun001 WAY=optasm is failing -------------------------------------+------------------------------------- Reporter: thomie | Owner: Type: bug | Status: closed Priority: highest | Milestone: 8.0.1 Component: Compiler | Version: 7.11 Resolution: fixed | Keywords: Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: None/Unknown | Test Case: | base/tests/exceptionsrun001 Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Phab:D1616 Wiki Page: | -------------------------------------+------------------------------------- Comment (by simonpj): `catch` is ''not'' strict in its argument. Its argument is a function; `catch` just guarantees to call that function. So yes `build (...)` is sure to be evaluated, but GHC doesn't aggressively evaluate things as early as possible. It just uses strictness info to avoid building thunks; and none are built here. So I think it's fine. Might be wroth fixing the test though. Thanks for the accurate diagnosis.
