9262,windows_intermodule_singleton breaks when calling a Debug dll from a Release executable,Lars Hagström <lars@…>,Ion Gaztañaga,"A simplified example of what goes wrong (the reality is more complex, and also very difficult for me to change):

On Windows I have an exe and a dll that both use boost.interprocess. The dll interface is C-like, so that the exe and dll can use different runtimes (i.e. Debug and Release runtimes).
This works fine as long as I comment out the BOOST_INTERPROCESS_HAS_KERNEL_BOOTTIME define in workaround.hpp. But if I leave that define in the code I will get random access violations deep inside the tmp_folder function (or one of the other functions in tmp_dir_helpers).

I believe that this is due to the windows_intermodule_singleton, which is only used when ...HAS_KERNEL_BOOTTIME is defined. This singleton will get created in one runtime and then accessed in another, which does not work since it contains a std::map, which is an STL object that is not possible to pass between runtimes in Visual C++.

If it is possible to fix this that would be great, but the other option would be a ""nicer"" way to turn off the singleton without having to patch one of the boost headers.",Bugs,reopened,To Be Determined,interprocess,Boost 1.54.0,Problem,,,
