Don't use gcc 3.0.x. It will dump core on the following code:
switch(foo) {
default:
blah();
break;
}
You don't want to know how many places code like this exists in
our source tree much less in 3rd party software. :) Just make
sure you have gcc 3.1.x which has this bug fixed. It doesn't look
like gcc 3.1 is in ports (probably cause there's no released version
of it yet). However, if you really want to, you can install the
gcc30 port, and build by doing 'make CC=gcc30'.
