Trouble Setting POST_MAX

[jonathan vanasco]

	preface -- sorry if this is a double post, i accidentally sent from 
another address earlier, and i believe this list doesn't post 
non-subscriber messages.

Admittedly, this is due to user error and incompetence
mod_perl2 / apache2 / libaprq is the latest
This works:
        sub handler
        {
                my      $r      =       shift;
        };
Based on the examples in the book/cookbook and online, I thought I was 
supposed to do this:
sub handler
{
	my  $r 	= 	Apache::Request->new(shift,
				POST_MAX        => .1 * 1024 * 1024,    # in bytes, so 100K
				DISABLE_UPLOADS => 0
				);
}

That turns into a segfault.
can someone point out my mistake?
