#900: Regression in latest Cabal-1.13.3 snapshot
----------------------------+-----------------------------------------------
Reporter: guest | Owner:
Type: defect | Status: new
Priority: normal | Milestone:
Component: Cabal library | Version: 1.8.0.6
Severity: major | Keywords:
Difficulty: unknown | Ghcversion:
Platform: |
----------------------------+-----------------------------------------------
The following cabal file below triggers an assertion fail on the second
install:
{{{
$ cabal --version
cabal-install version 0.13.3
using version 1.13.3 of the Cabal library
$ cabal install
Resolving dependencies...

cabal: Distribution/Simple/PackageIndex.hs:123:8-13: Assertion failed
}}}
Only when I unregister the installed package via `ghc-pkg unregister
foobar` I can configure the package again...
The cabal file causing this behaviour:
{{{
name: foobar
version: 0.2.0-git20111120
synopsis: none
license: BSD3
license-file: LICENSE
author: foo
maintainer: foo@bar
build-type: Simple
cabal-version: >=1.10
library
default-language: Haskell2010
exposed-modules: FooBar
build-depends: base
}}}
The `FooBar` module is just a dummy empty module. This used to work
previously, e.g. with
{{{
$ cabal-0.11.2 --version
cabal-install version 0.11.2
using version 1.12.0 of the Cabal library
}}}
