I have been testing Oval on Fedora Core 11 on PowerPC. When I run the interpreter against some of the definition files I get a segfault. I tried to do a little analysis with gdb but debugging the code is really outside of the scope of what I can do. Here is some of the debug output and a backtrace:
Program received signal SIGSEGV, Segmentation fault.

Could you post a definition that is causing OVALDI to seg fault?
Thanks,
