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
