php 4.0.3pl1 and pdflib 3.02

Ive having a problem getting everything to work right, it all was working hunky dory, for awhile, then today I find that generating pdfs gives apache 3.3.12 agood old segfault. specifically pdf_set_font($pdf, "Times-Roman", 10, 'winansi', 1); causes the fault. Ive configured php with configure \ --disable-debug \ --enable-versioning \ --enable-trans-sid \ --enable-sockets \ --enable-ftp \ --with-mhash \ --with-mcrypt \ --with-apxs \ --with-mysql \ --with-jpeg-dir=/usr/local \ --with-xpm-dir=/usr/X11R6 \ --with-png \ --with-tiff \ --with-zlib \ --with-gd \ --with-ttf \ --with-pdflib \ --with-t1lib \ and pdflib 3.02 with configure --enable-shared-pdflib everything compiled and installed witout any errors. Any idea's? Chris Lee
