#9128: Possible bug in strictness analyzer when where clause declared NOINLINE ---------------------------------+----------------------------------------- Reporter: aalevy | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 7.8.2 Resolution: | Keywords: strictness bytestring Operating System: | Architecture: Unknown/Multiple Unknown/Multiple | Difficulty: Unknown Type of failure: Runtime | Blocked By: crash | Related Tickets: Test Case: | Blocking: | ---------------------------------+----------------------------------------- Comment (by aalevy): Yes, sorry. From a fresh install with ghc-7.8.2 and cabal (1.20 in my case, but since it's just for installing dependencies, and I don't think default optimization levels have changed recently, I suspect it doesn't matter): 0. Prerequisites: postgresql (I'm using 9.3, but probably doesn't matter) with tools (specifically pg_ctl). Tools, for example, are not installed by default on the postgresql version that comes with OS X -- you have to install from homebrew I think. pg_ctl comes with postgresql on most distros of linux though. Unfortunately, I don't know about windows and don't have an install available to test with. 1. Grab the unpatched version of the postgresql-orm from github: {{{ $ git clone https://github.com/alevy/postgresql-orm.git $ cd postgresql-orm $ git checkout 93075d56ae5ffeb8f80ecc8c01436713c2656a6b }}} 2. Install library dependencies (inside a cabal sandbox if you care about not polluting your global environment): {{{ $ cabal sandbox init $ cabal install --only-dependencies }}} 3. Copy test.hs into the project directory 4. Compile with O1: {{{ $ ghc -O1 test.hs -package-db ./.cabal-sandbox/x86_64-linux- ghc-7.8.2-packages.conf.d }}} 5. Run: {{{ $ ./test test: Oops! Entered absent arg a_sYDl{v} [lid] bytestring-0.10.4.0:Data.ByteString.Internal.ByteString{tc r5T} }}} All the machines I've tested this on are running Arch Linux, with ghc-7.8.2 Are there any steps I haven't thought to include?
