#13243: make test in non-validate configuration fails with a variety of ghci errors -------------------------------------+------------------------------------- Reporter: bgamari | Owner: Type: bug | Status: new Priority: normal | Milestone: 8.4.1 Component: GHCi | Version: 8.0.1 Keywords: | Operating System: Unknown/Multiple Architecture: | Type of failure: Other Unknown/Multiple | Test Case: | Blocked By: Blocking: | Related Tickets: Differential Rev(s): | Wiki Page: -------------------------------------+------------------------------------- Starting with a fresh checkout of `ghc`, testing in a non-validate configuration fails in a rather peculiar way. e.g., {{{ $ ./boot $ ./configure $ make $ make test }}} Results in a number of test failures of the `ghci` way which suggest that GHCi is having trouble identifying types. e.g., {{{ =====> break026(ghci) 50 of 101 [0, 46, 0] cd "./ghci.debugger/scripts/break026.run" && HC="/mnt/work/ghc/ghc- testing/inplace/test spaces/ghc-stage2"
