Bug#749136: jellyfish: FTBFS with clang instead of gcc

[Alexander Ovchinnikov]

Package: jellyfish
Severity: minor
Tags: patch
User: pkg-llvm-t...@lists.alioth.debian.org
Usertags: clang-ftbfs

Hello,

Using the rebuild infrastructure, your package fails to build with clang 
(instead of gcc).
See build logs here: 
http://clang.debian.net/logs/2014-01-14/jellyfish_1.1.10-1_unstable_clang.log

Thanks,
Alexander
