Bug#737459: g++-4.7 [wheezy] may cause link failure when using lambda functions

[Darren Salt <bugspam@moreofthesa.me.uk>]

Package: g++-4.7
Version: 4.7.2-5
Tags: fixed-upstream, wheezy

I just hit this one today when building Unvanquished in a wheezy chroot.
We've worked around it by enclosing the ‘offending’ class in an anonymous
namespace.

/tmp/buildd/unvanquished-0.24.0/src/engine/framework/FileSystem.cpp:905:
undefined reference to `FS::ZipArchive::Open(Str::BasicStringRef<char>,
std::error_code&)::{lambda(void*, void const*, int)#1}::_FUN(void*, void
const*, int)'
