#15396: -staticlib is broken on GHC 8.4.3 on Linux under certain conditions -------------------------------------+------------------------------------- Reporter: RyanGlScott | Owner: (none) Type: bug | Status: new Priority: normal | Milestone: 8.6.1 Component: Compiler | Version: 8.4.3 (Linking) | Resolution: | Keywords: Operating System: Linux | Architecture: Type of failure: Compile-time | Unknown/Multiple crash or panic | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Description changed by RyanGlScott: Old description:
When compiling this simple program:
{{{#!hs main = pure () }}}
Using the `-staticlib` flag on GHC 8.4.3 on Linux, it panics if using a certain toolchain:
{{{ $ lsb_release -a No LSB modules are available. Distributor ID: Ubuntu Description: Ubuntu 14.04.5 LTS Release: 14.04 Codename: trusty $ /opt/ghc/8.4.3/bin/ghc -staticlib Bug.hs Linking Bug.a ... ghc: panic! (the 'impossible' happened) (GHC version 8.4.3 for x86_64-unknown-linux): Data.Binary.Get.runGet at position 27462987: Invalid archive header end marker CallStack (from HasCallStack): error, called at libraries/binary/src/Data/Binary/Get.hs:351:5 in binary-0.8.5.1:Data.Binary.Get }}}
I say "certain toolchain" since I am able to reproduce this issue on Ubuntu 14.04, but not 18.04:
{{{ $ lsb_release -a No LSB modules are available. Distributor ID: Ubuntu Description: Ubuntu 18.04 LTS Release: 18.04 Codename: bionic $ ghc -staticlib Bug.hs [1 of 1] Compiling Main ( Bug.hs, Bug.o ) Linking Bug.a ... }}}
This issue does not occur on GHC 8.2 and earlier:
{{{ $ /opt/ghc/8.2.2/bin/ghc -staticlib Bug.hs [1 of 1] Compiling Main ( Bug.hs, Bug.o ) Linking Bug.a ... Static archive creation only supported on Darwin/OS X/iOS }}}
Commit b8f33bc6b738b0378976e42b79369f0e53b680c7 allowed the use of `-staticlib` on all platforms. angerman, do you know what might be happening here?
