#7820: Installing profiling library BREAKS non-profiling executable ----------------------------+----------------------------------------------- Reporter: rrnewton | Owner: igloo Type: bug | Status: closed Priority: normal | Milestone: 7.8.1 Component: Compiler | Version: 7.6.2 Resolution: invalid | Keywords: profiling Os: Linux | Architecture: x86_64 (amd64) Failure: Runtime crash | Difficulty: Unknown Testcase: | Blockedby: Blocking: | Related: ----------------------------+----------------------------------------------- Changes (by igloo): * status: new => closed * resolution: => invalid Comment: Aha, if you look at the `-v` output of `cabal-install`, then you can see that it only builds `cbits/primops.cmm` once (rather than separately for each way), and with profiling enabled it's compiled with `-prof`. This presumably means that some structure is the wrong size for teh vanilla way, leading to a segfault. So this looks like a bug in Cabal rather than GHC.
