boost unique_lock has no mutex

Description (last modified by )
This is an issue I am observing in the newly released boost_1_58 library. I suspect the problem may not be boost related, and could be an msvc 12.0 compiler related issue. The symptom I observe is that when a Visual C++ project TURNS ON one of the compiler optimization flags /Og, /O1, /O2 or /Ox Flags, the C++ code that I am using below is throwing an exception:
Below is the sample code I use in the application:
boost::mutex::scoped_lock <Scoped Lock Variable> (<Mutex Object>)
Below is the exception message I am seeing which strangely occurs the second time a scoped lock is called on the same valid Mutex Object within the application:
"boost unique_lock has no mutex"
I am baffled by what causes this problem. When I turn off the optimization flags and execute the program, the application executes flawlessly. Only when I turn on optimization flags, this error consistently occurs. Workaround I am using is to disable optimization Flags for the release version.
Below is my build configuration:
Visual Studio community edition 2013, which uses msvc 12 compiler version; Windows 8.1; boost Library version 1.58
