     Type:  Bugs                        |     Status:  new
Milestone:  To Be Determined            |  Component:  coroutine
  Version:  Boost 1.55.0                |   Severity:  Problem
 Keywords:  pull_coroutine_base; crash  |
----------------------------------------+-----------------------
 Using 1.55b1 coroutine a sporadic crash occurs when running outside of the
 debugger. Appears related to creating the coroutine context. The attached
 test application creates N threads which execute coroutines.

 Platform: Windows 7 x64[[BR]]
 Compiler: vc2012 [[BR]]
 Build: x64 [[BR]]
 Note: Occurs outside of debugger ~ 1 in 10 executions of application on an
 Intel i7[[BR]]

 Educated guess: [[BR]]
 It may be some sort of race condition where a coroutine context is being
 created at the same time in two threads that are resident on the same
 processing core.
