[Boost-users] M68K-Coldfire: Boost 1.44 seems to have a problem with low level locking

Hello,

I recently upgraded boost on my embedded linux platform (m68k coldfire  
architecture)
from version 1.41 (cmake release) to 1.44.
Boost itself compiles flawlessly but when I tried to link my application
(which makes use of the thread, regex, system libraries) it fails with  
(note the last line):

squ_loopback_timer.o: In function  
`boost::asio::detail::wait_handler<boost::_bi::bind_t<void,  
boost::_mfi::mf1<void, rapp::squ_loopback_timer_t,  
boost::system::error_code const&>,  
boost::_bi::list2<boost::_bi::value<rapp::squ_loopback_timer_t*>,  
boost::arg<1> > >  
 >::do_complete(boost::asio::detail::task_io_service*,  
boost::asio::detail::task_io_service_operation*,  
boost::system::error_code, unsigned int)':

`__sync_lock_test_and_set_4'

What changed about the locking mechanism?
Btw. I'm also using boost version 1.38 in another project (but on the  
same platform).
My compiler is g++ version 4.2.0 20070318 (prerelease) (Sourcery G++  
Lite 4.2-35).

Any hints or help is appreciated!

Best regards
