r37927 segfaults on building lua

[protein_origami]

I had this problem on parrot 1.0.0, and confirmed that I have the same problem in 37927. The lua (commit 56008066d68415d10dfbd97326654ed19c514372) build proceeds smoothly up until:

/usr/local/parrot/r37927/bin/parrot -o lua.pbc lua.pir make: *** [lua.pbc] Segmentation fault

Here's the stack trace:
