Hi, I have a strange bug here. I am using singleton_pool and it crashes at a call to singleton_pool::ordered_malloc in multithreaded mode. The funny thing is I am locking a mutex before the call and it still crashes. The test file can be found here: https://svn.boost.org/svn/boost/sandbox/block_ptr/libs/smart_ptr/example/thr... And the calls to the pool (allocate & deallocate) a made from class "pool" of the following file: https://svn.boost.org/svn/boost/sandbox/block_ptr/boost/detail/block_base.hp... The backtrace I get is: #0 0x0000000000407842 in boost::simple_segregated_storage<unsigned long>::try_malloc_n (start=@0x42e7ddc0, n=10, partition_size=8) at /home/vnmr1/phil/boost_1_46_1/boost/pool/simple_segregated_storage.hpp:236 #1 0x00000000004078f7 in boost::simple_segregated_storage<unsigned long>::malloc_n (this=0x614d88, n=11, partition_size=8) at /home/vnmr1/phil/boost_1_46_1/boost/pool/simple_segregated_storage.hpp:260 #2 0x000000000040c2ab in boost::pool<boost::default_user_allocator_new_delete>::ordered_malloc (this=0x614d88, n=88) at /home/vnmr1/phil/boost_1_46_1/boost/pool/pool.hpp:527 #3 0x000000000040c9b8 in boost::singleton_pool<boost::detail::sh::pool, 1u, boost::default_user_allocator_new_delete, boost::details::pool::pthread_mutex, 32u, 0u>::ordered_malloc (n=88) at /home/vnmr1/phil/boost_1_46_1/boost/pool/singleton_pool.hpp:72 #4 0x000000000040d937 in boost::detail::sh::pool::allocate (s=88) at ../../../boost/detail/block_base.hpp:150 #5 0x000000000040d9cd in boost::detail::sh::block<std::pair<int, int>

Anybody has any idea? Thanks, -Phil
