No luck on comp.lang.c++ or stackexchange, so why not try here

I want to hand my students a few variations of a C++ class=20
implementation, each with a different bug. Their task is to write a set=20
of tests and use them to identify each bug.

The students use different compilers, so it is not practical to hand=20
them object files. Are there any free C++ Source Code Obfuscators that I=20
could use to hide the bugs I introduced in each version of the cpp file?=20
(Without obfusciation a simple diff would reveal the differences.)

BTW any other way to distribute compilable source to my students without=20
immediately reveling the differences would be welcome too!
