#15068: Small number of test case failures on Ubuntu Bionic (GCC 7.3) -------------------------------------+------------------------------------- Reporter: jrp | Owner: (none) Type: bug | Status: merge Priority: highest | Milestone: 8.6.1 Component: Compiler | Version: 8.4.1 (CodeGen) | Resolution: fixed | Keywords: Operating System: Linux | Architecture: x86_64 | (amd64) Type of failure: Incorrect result | Test Case: T13658 at runtime | T14779a T14779b T14868 debug | parsing001 Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Phab:D4654 Wiki Page: | -------------------------------------+------------------------------------- Comment (by svenpanne): I think that none of the suggestion so far is very helpful in the long run, the raw numbers (e.g. DistroWatch, State of Haskell Survey) indicate that this problem is a show stopper for 8.4.2 and its presence alone is a reason for an 8.4.3 release: Stack is by far the most popular way to install GHC, stack is far more popular as a build tool than cabal, and Ubuntu is ranking among the top 3 (or 4, depending on the survey) Linux distros, with 18.04 even being an LTS release. Put another way: Installing and using GHC in one of the most probable ways according to surveys will lead to a fragile/broken installation. Installing a GHC by hand or changing the default GCC (which will definitely lead to problems later and undermines the whole idea of an LTS release) is OK as a stopgap measure, but not a real solution until August. I am sure everyone on this list is able to work around the problems, but I worry more about the average/wannabe Haskell user. Would it really be that hard to release an 8.4.3 with just the single fix above cherry-picked? -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/15068#comment:27 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
