After a bit of looking it seems the problem is
with preloading body Mail::IMAPClient::BodyStructure and FileHandle.

Preloading one or the other seems fine but both causes problems.

I'm using debian stable with

Parse::RecDescent 1.80
FileHandle v 2.0
Mail::IMAPClient::BodyStructure v 0.01
perl v 5.005

Could the problem be that the grammer is spicified using a here document?
I seem to recall problems related to this with Inline::C ( I don't remember
any
mention of modperl ).

Some of the demo scripts with RecDescent such asdemo_simpleXML.pl
seem to have problems under modperl because of there use of data sections
at the end of the file.

Sorry about that,I should have checked the man page.
The question was just an after thought.
Precompiling the parser seems to half the time used in using it.
Creates quite a large module,I'd hate to see what a large grammer would
create.
