#5846: Boost::Test: intermittent crash during testing

 Reporter:  anonymous         |       Owner:         
     Type:  Bugs              |      Status:  new    
Milestone:  To Be Determined  |   Component:  None   
  Version:  Boost 1.47.0      |    Severity:  Problem
 Keywords:                    |  
------------------------------+---------------------------------------------
 Our tests spin up 64 threads and then exercise various objects. Upon
 thread exit, the thread prints a simple message (args.id is the internal
 thread number):

 {{{
 BOOST_MESSAGE( "Thread " << args.id << " completed" );
 }}}

 The problem is tough to reproduce, but I've got one under the debugger. It
 appears Boost::Test has missed a lock in execution_monitor.

 We are compiling with both CXXFLAGS += -D_REENTRANT and LDLIBS +=
 -lpthread. Boost::Test compilation page
 (http://www.boost.org/doc/libs/1_47_0/libs/test/doc/html/execution-

 monitor/compilation.html) does not specify any additional flags for
 multithreaded testing, and the FAQ
 (http://www.boost.org/doc/libs/1_47_0/libs/test/doc/html/faq.html) does
 not mention any special steps.

 === Console 1 ===
 $ ./test/run_esapi_tests
