Comment 7 for bug 544636

Johann Felix Soden, thank you for the patch. I have tried it, but after patching pdftopdf pdftopdf dumps core:

cat ~/ghostscript/gpl/testfiles/CityMap-evince.pdf | PPD=/etc/cups/ppd/pxl.ppd /usr/lib/cups/filter/pdftopdf 1 1 1 1 "" > ~/ghostscript/gpl/testfiles/CityMap-evince-pdftopdf2.pdf*** glibc detected *** /usr/lib/cups/filter/pdftopdf: free(): invalid pointer: 0x00007fefeed46b88 ***

It always dumps core, independent of the input file and the PPD file. The backtrace in gdb is:

#0 0x00007f3aa7c20a85 in raise () from /lib/libc.so.6
