Maybe you are expecting 'text' values to be null-terminated? They are
not. You might look into using TextDatumGetCString or related functions
to convert.

PS: the chances of us accepting a contrib module that requires
significant unusual infrastructure to build seem pretty low from
where I sit. You're certainly free to do whatever you want for
private work, or even for a pgfoundry project --- but if you do
have ambitions of this eventually becoming contrib, "it's easier"
is not going to be sufficient rationale to not use bison/flex.
