[Rcpp-devel] bug hunting

[Romain Francois]

Hello,

I think the bug reported by Doug in the "Extract a function from a list 
and create a call" thread is now fixed.

The problem was Vector did not have copy constructor and assignement 
operators, so the compiler did generate silly ones for us. Do the vector 
cache was not updated, so the string_proxy was holding an innapropriate 
VECTOR*.

Please let me know if this works now.

In this debuggin battle, I defined the macro RCPP_DEBUG which is similar 
to logTxt but allows printf formatting on the text and also the DEMANGLE 
macro that demangles a c++ class name.
