------------------------------------------------+---------------------------
 The errors below refer to GCC 4.4, Boost 1.37 running on Linux.

 When I try to compile the simplest code that needs to link against Boost
 libraries with GCC using OpenMP and GCC's parallel mode, I get linking
 errors. The -D_GLIBCXX_PARALLEL below is key (the problem goes away
 without it).

 Is this a known problem, and are there any fixes? The problem is not
 specific to program_options, I get similar errors with the serialization
 library.

 For example:
 g++ -O3  witnessed.cpp -o witnessed-openmp -fopenmp -D_GLIBCXX_PARALLEL
 -lboost_program_options
 results in
