I've attached an minimal example project to demonstrate the problem. The package includes static boost libraries that were built with steps given below. This example produces a thedll.dll that links libboost_thread (does not use any headers) and then theexe.exe that links to thedll.dll. theexe.exe fails to start with attached error prompt. Root cause of the fail is beyond me, but I traced debugger to dll_dllmain.cpp on line 57. Here _initterm_e returns non-zero value and thedll.dll init fails. ```This happens only if libboost_thread is linked to the dll```.
