Considering the error message, and the fact it happens during compilation, I highly suspect this is a gcc bug. I would first try to upgrade gcc, and if that doesn't work, to downgrade gcc. If you still get a segmentation fault with the newest versions of gcc, submit a bugreport to the gcc team (as instructed in the message you quote), and a FYI report to p5p. (It's good that p5p knows about this issue. Perl contains a lot of code that works around bugs in compilers and libraries. That doesn't mean Perl will be patched to avoid a segfault in a specific version of gcc though, but the issue might get mentioned in a README file. (Too bad you discover this after 5.8.1 was released, not before)).
