------- Comment #4 from pluto at agmk dot net 2010-04-18 13:44 -------
during analysis the boost::thread::start_thread() function which causes
invalid writes detected by valgrind i've noticed that gcc-4.5 generates
bigger and more complex code of this function with few more lock'ed opcodes.
afaics gcc-4.5 produces some mess for boost::shared_ptr.
could please someone look at this? it may be a missed optimization or other
bug.
