crunchgen and c++

[Frank Zerangue]

Is crunchgen compatible with c++ executables?

I was able to build the c++ tool into a crunched binary but get an illegal instruction trap when trying to execute the tool. And static variables in the c++ tool are initialized when any of the binaries crunched are executed.

Thanks for any ideas on this matter.

I thik you answer yourself...

Clearly not :-)

To stop that happening the linker section names for the initialiers
(and destructors) in each tool would need renaming, and then the
constructors run (in the correct order) before calling the tool's main().
(and even that might not work).

I'd try a minimal crunched binary and see why it fails.
All crunchgen really does is rename the program's symbols so that
the ones from each 'tool' are separate.
