Package: ghc
Version: 7.10.3-2
Severity: normal
Tags: patch
User: [email protected]
Usertags: origin-ubuntu ubuntu-patch xenial
The newly-bootstrapped Ubuntu s390x architecture has its toolchain
configured to use PIE by default (I presume by customer request, though
I don't know the details). Binaries built by GHC segfault immediately
if PIE is in use. I think it would make sense to just disable PIE on
s390x; it's not enabled by default on Debian s390x, but -fno-PIE/-no-pie
should be harmless.
Disabling this both during the GHC build itself and for things that the
resulting /usr/bin/ghc compiles requires a couple of different pieces.
Here's a tested patch (which could be refactored later if more
architectures have this problem in future):
