Description
Dear folks,
I am trying to debug sporadic access violations that occur inside a boost::interprocess message queue. (access violation reading an address in the shared memory region).
Environment: boost 1.54, VC++2010. Occurs in both Debug & Release builds.
It always occurs on or about line 854 (in case of reception) in message_queue.hpp: Comments were added by me
recvd_size = top_msg.len; top_msg points to invalid location
Or line 756 (in case of sending)
BOOST_ASSERT(free_msg_hdr.priority == 0); free_msg_hdr points to invalid location
Please see this S/O link for the entire question, plus sample code that reproduces the problem for me:
