Here's how it can be reproduced "in place" with upstream ghostscript.
Simplifications welcome.
Recipe:
... install ghostscript build-deps, ttf-sazanami-mincho, etc ...
$ git clone git://git.ghostscript.com/ghostscript.git
$ cd ghostscript/gs
$ ./autogen.sh -C \
--with-fontpath=/var/lib/ghostscript/fonts:\
/usr/share/cups/fonts:/usr/share/ghostscript/fonts:\
/usr/local/lib/ghostscript/fonts:/usr/share/fonts \
--disable-compile-inits --prefix=/usr
$ (cd /usr/share/ghostscript && ln -sT /tmp/ghostscript/gs 9.01)
$ rm Resource/Init/cidfmap
$ make -j2
$ sed -i -e 's,exec "$GS_EXECUTABLE",exec gdb --args bin/gs,'
lib/ps2pdfwr
$ lib/ps2pdfwr ghostscript-ps2pdf-crash.ps
Result:
Starting program: bin/gs -P- -dSAFER -q -P- -dNOPAUSE -dBATCH
-sDEVICE=pdfwrite -sstdout=%stderr -sOutputFile=ghostscript-ps2pdf-crash.pdf
-P- -dSAFER -c .setpdfwrite -f /tmp/ghostscript-ps2pdf-crash.ps
[Thread debugging using libthread_db enabled]
Program received signal SIGSEGV, Segmentation fault.
pdf_set_charproc_attrs (pdev=0x89ca124, font=0x9d9b608, pw=0xbfffe140,
narg=2, control=TEXT_SET_CHAR_WIDTH, ch=161)
at ./base/gdevpdti.c:578
578 pcp->owner_fonts = NULL;
(gdb)
pcp (= pdev->accumulating_substream_resource) is null, hence the segfault.
Further reading:
git log --follow -G pdf_set_charproc_attrs base/gdevpdti.c
git log -G accumulating_substream_resource
[one can instead use "git log -p" and grep by hand if using
pre-1.7.4 git]
Well, that's a start. Thanks again.
