*ping*
Hi Steven,
the following code used to compile with older gcc versions (I just tried with 4.5 and I used the same construct with 4.7) but no more with gcc 4.8, but I don't know whether it's a gcc or type_erasure problem (or mine). The problem seems to be with rvalue refs. If I use the commented out version, it compiles fine on both compilers. Any idea? If you have no gcc 4.8, I can attach the error.
Thanks, Christophe
