When trying to use the --optimize flag, building perl6 causes parrot to
segfault. Attached is the Configure.pl script output. Below is a backtrace
by manually performing the make step from gdb. You'll notice the second run
performs the same operation with the -G option to disable memory management.
Seperate executions have generated slightly different backtraces (likely due
to signal timings). This is not caused by the --inline Configure.pl option.

Hello, I'm Configure. My job is to poke and prod your system to figure out
how to build Parrot. The process is completely automated, unless you passed in
the `--ask' flag on the command line, in which case I'll prompt you for a few
pieces of info.
Since you're running this program, you obviously have Perl 5--I'll be pulling
some defaults from its configuration.
