[Signals] Boost.signals dll version crashes on OS X

17 Aug 2005

      I built the boost.signals library using bjam and am trying to use it
in an xcode project named TestSignals.  The project only consists of
the signals library and the maximum.cpp example file
(boost-root/libs/signals/example/maximum.cpp).  The project builds but
it crashes with a SIGBUS signal 10 when run.  This only happens with
the dynamic version of signals.  I have defined BOOST_SIGNALS_DYN_LINK
and built the library multithreaded, so I'm not sure what I'm doing
wrong.  I'm running OS X 10.4.2 with Xcode 2.1.

Here is a snippet of the crash log (I can post the rest on request):

Exception:  EXC_BAD_ACCESS (0x0001)

boost::any) + 76 (function_template.hpp:119)

Any help would be much appreciated.
