Hello,

I have a simple OpenGL program that is using Boost Threads and I had it 
working fine under Boost 1.34. I have switched to 1.36 for some of the 
newer mutex locking functionality and everything works fine, but.. I 
keep getting an invalid memory access error. My program will run fine if 
i skip past the offending call.

Wondering if anyone has any ideas?

The offending call happens when the rendering thread is created. The 
call stack is as follows:

  Access in invalid memory in process: solarsystemT.exe(4056)  - 
:\development\boost_1_36_0\boost/thread/win32/once.hpp#125
  Attempt to access 4 byte(s) at 0x00417084.
    0x00411056 - E:\development\boost_1_36_0\boost/thread/win32/once.hpp#125
    0x0041137B - 
E:\development\boost_1_36_0\libs\thread\src\win32\thread.cpp#44
    0x00411A61 - 
E:\development\boost_1_36_0\libs\thread\src\win32\thread.cpp#151

The memory that boost::call_once is accessing is 
current_thread_tls_init_flag
created earlier by boost::once_flag 
current_thread_tls_init_flag=BOOST_ONCE_INIT;

I can see that this flag was created and initialized to zero.

Thank you for any insight.
