Hi!

BOOST_PP_ARRAY_PUSH_BACK & BOOST_PP_ARRAY_PUSH_FRONT on empty array
leads to invalid code if Boost 1.49 is used.

In 1.48 and older it works as expected.

An incident was already filed and a sample attached:
https://svn.boost.org/trac/boost/ticket/6760

Thanks for solving. Let me know if I can be of further assist.
