Antony,

Thanks a lot for your answer. But I check the configuration of each project, and same runtime-library is used (/MDd) in both cases. So my problem doesn't come from here. If you have another idea...

Thanks for your help, Sébastien

You are linking to the static Boost.Thread library. This means that you've got two distinct Boost.Thread libraries loaded into your process, one into the executable and one in the DLL. This means, among other things, that the internal book-keeping data of the library is duplicated and separated, in ways that tend to violently break once you try to interact across module boundaries, particularly if you're doing something that relies on RTTI/EH. -- Lars Viklund | zao@acc.umu.se
