Bug#765575: hidden symbol `.LTHUNK15.4817' isn't defined

[Mathieu Malaterre <malat@debian.org>]

Package: gcc,libboost-program-options-dev
Version: gcc/4:4.7.2-1
Version: libboost-program-options-dev/1.49.0.1
Severity: important

For some reason I cannot compile and link to a boost lib using -flto
-Ofast (everything is fine when each is taken separatly). I am
assigning to both packages, feel free to re-assign to the proper one.

Steps:
$ g++  -flto -Ofast -o demo demo.cxx -lboost_program_options
