To make progress against this, you'll have to look at the build logs, or let others look at them. Before doing that, I would try to build the affected packages outside of portage, saving the output of "configure" and "make". If you also see the problem that way, try with the stable gcc and compare logs. BTW alloca() is a very peculiar way of allocating memory and only a few packages use it, fortunately. -- Please don't Cc: me privately on mailing lists and Usenet, if you also post the followup to the list or newsgroup.
