The problem is that this line references an non-existent variable 'size', there is a similar construct at line 544 that uses 'size_arg' instead so my guess is that this is probably the solution in this line also. Another possible solution suggested by the compiler is adding '()' and make it a call to the 'size' method instead. " Bugs closed To Be Determined signals2 Boost 1.48.0 Problem fixed
