hello,

i've built 5.17.2 doubles from source on osx 10.7.  using the old
parser** everything compiles without complaints, but i'm getting
segfaults when using a very large orchestra which includes a fair
amount of python code (encased in pyruni), long instruments and a
s**tload of strsets.  the orchestra is a little too unwieldy for me to
post in a way that others could run it, but here is the code:
http://pastebin.com/iYG27cR0

i feel as though i am running into issues of orch length since
everything works fine until i add a few too many chars of python code.
 below is the error message i get when i do:

**with buildNewParser=1 i get a segfault with fairly simple macros
which are defined in includes.  i'll try to work up a portable example
of that soon.

thanks in advance for any suggestions,
