When I run your code I get:
4
#<void* #2 0x3a1378>
#<foo* #3 0x3a1378>
#<void* #4 0x3a1378>
#<foo* #5 0x3a1378>
So the results are the same (except for the fact that the type tag is
either void* or foo*). What is the result your get?
I suspect that you did not compile Gambit using --enable-cplusplus .
If you want to load code compiled by a C++ compiler, then Gambit
itself must have been compiled with a C++ compiler (so that the ABI is
the same).
