Bart, Thank you again! I recompiled boost from source using: bjam variant=debug define=BOOST_LOG_USE_CHAR install and all the above warnings are gone. When I run the program, half of the time I get a clean output, the other 10% of the time I get the following: ==14837== drd, a thread error detector ==14837== Copyright (C) 2006-2010, and GNU GPL'd, by Bart Van Assche. ==14837== Using Valgrind-3.6.0.SVN and LibVEX; rerun with -h for copyright info ==14837== Command: ./a.out ==14837== ==14837== Thread 3: ==14837== Conflicting load by thread 3 at 0x05d8a288 size 8 ==14837== at 0x5B78ECE: __nptl_deallocate_tsd (pthread_create.c:153) ==14837== Allocation context: BSS section of /lib/libpthread-2.11.1.so ==14837== Other segment start (thread 2) ==14837== at 0x58E1001: clone (clone.S:84) ==14837== Other segment end (thread 2) ==14837== at 0x4C2F283: pthread_mutex_lock (drd_pthread_intercepts.c:578) ==14837== by 0x4E53985: boost::pthread::pthread_mutex_scoped_lock::pthread_mutex_scoped_lock(pthread_mutex_t*) (pthread_mutex_scoped_lock.hpp:25) ==14837== by 0x4E556A4: void boost::call_once<void (*)()>(boost::once_flag&, void (*)()) (once.hpp:55) ==14837== by 0x4E50938: boost::detail::set_current_thread_data(boost::detail::thread_data_base*) (thread.cpp:105) ==14837== by 0x4E509C3: thread_proxy (thread.cpp:118) ==14837== by 0x4C2EA60: vgDrd_thread_wrapper (drd_pthread_intercepts.c:272) ==14837== by 0x5B798B9: start_thread (pthread_create.c:300) ==14837== by 0x58E103C: clone (clone.S:112) ==14837== ==14837== ==14837== For counts of detected and suppressed errors, rerun with: -v ==14837== ERROR SUMMARY: 1 errors from 1 contexts (suppressed: 130 from 130) ------------------------------------------------------------------------------ ThinkGeek and WIRED's GeekDad team up for the Ultimate GeekDad Father's Day Giveaway.
