Hi ! I just got round to finally debug some mysterious failures on my project against current trunk. It seems that ------------------------------------------------------------------------ r57953 | pdimov | 2009-11-26 21:55:05 +0100 (Thu, 26 Nov 2009) | 1 line Add error checking to lwm_pthreads.hpp. Refs #2681. ------------------------------------------------------------------------ broke BOOST_SP_USE_QUICK_ALLOCATOR support. All my programs (and tests) using smart_ptr fail with /rmc/hunold/packages/boost/boost/smart_ptr/detail/lwm_pthreads.hpp:73: boost::detail::lightweight_mutex::scoped_lock::scoped_lock(boost::detail::lightweight_mutex&): Assertion `pthread_mutex_lock( &m_ ) == 0' failed. on exit. Steps to reproduce: I've attached against the Jamfile.v2 in libs/test/test which adds an extra feature "quick-allocate" with values "off" "on" Running "bjam quick-allocate=on" will start a build using the quick allocator and reveal 4 failures (log attached). I'm lost here. All I have figured out so far is that the destruction of static object might be involved here. But this migt be a red herring. Any ideas on this ? This is catched by the regression tests as obviously noone ist running a build with BOOST_SP_USE_QUICK_ALLOCATOR enabled. I can provide gdb stacktrace when needed. Yours, Jürgen -- * Dipl.-Math.
