Boost Test (Boost 1.46.0) GCC 4.6.1 error: ambiguous overload for ‘operator[]’

[lshlyapnikov@…]

Compiling my project unit tests and getting the following error (used to compile with older GCC (4.4?)):

/usr/include/boost/test/impl/debug.ipp: In function ‘std::string boost::debug::set_debugger(boost::unit_test::const_string, boost::debug::dbg_starter)’:
/usr/include/boost/test/impl/debug.ipp:737:46: error: ambiguous overload for ‘operator[]’ in ‘boost::debug::{anonymous}::s_info.boost::debug::{anonymous}::info_t::m_dbg_starter_reg[boost::debug::{anonymous}::s_info.boost::debug::{anonymous}::info_t::p_dbg]’
compilation terminated due to -Wfatal-errors.

BTW, I am using c++0x settings.

Here are all my g++ flags: -fmessage-length=0 -pedantic-errors -Wall -Wextra -Wconversion -Wcast-qual -Wcast-align -Wwrite-strings -Wlogical-op -Wfatal-errors -std=c++0x -g
