Hi folks,

I have a problem with upgrading from boost version 1.33 to 1.34.
My code runs fine with 1.33, but when compiling and linking againt 1.34 I
get the following runtime error (backtrace):

<backtrace>

</backtrace>

Line 173 in fpCTPart.cpp is:
geomNode->sigPreLoad.connect(boost::bind(&fpCTPart::slotFilePreLoaded,
this));

Are there any changes between these to versions in the bind/signal library?
(Are they not backward compatible?)

Thanks in advance.
Regards,
David
