Bus Error on 32-Bit Solaris 8 when using FileFilter

Hi,

i'm running into a "Bus Error" when trying to index a pdf file with
swish-e 2.4.4. The System is a UltraSparc 5 Workstation with Solaris 8
32-bit and gcc 3.3.2 installed.

As you see in the filter.config below, swish-e scan's a directory and
indexes all files in there. there are a small pdf and the src/index.c
file for testing in this directory. 
if the directive is "IndexOnly c" the indexing works fine. But when
indexing the pdf, it crashes, no matter which program (_pdftohtml.pl or
pdftotext) is used. starting the programs from the command-line works
fine.
i did a gdb backtrace, the problems seems related to memory-allocating
or something, i hope you can figure this out better.
