It may well be the problem. I didn't see crashes, just hangs. You have
objects created inside the signals lib (non-multi-threaded) so it
doesn't create/initialise the lock member variables. There is then
header code which is compiled directly in your application
(multi-threaded even though you only use 1 thread) and so it tries to
access these non-existent locks in the objects created in single
threaded signals lib.
If you are going to use a multi-threaded application/run-time, you must
build/link the multi-threaded version of the boost libs also.
Because of the crash, you may still have another problem, but I would
solve this one first, then look for the next. I saw the hangs under
Borland C++ Builder, the bug may present itself in a different way under
VC++.
