Hello all,
I'm trying to get my printer (Samsung CLP500) working with CUPS/SpliX.
I'm on 5.2/i386 release (generic) but I seem to get the same issue on a
clean install of snapshot 22 Jan with updated packages.
On the 5.2 release build I'm using ghostscript-9.05, cups1.5.3p5,
gstoraster-1.04p0 and splix2.0.0p6; plus the clp500.ppd, .cms and .cms2
files from the SpliX build/site.
When I try to print a simple plain text file the CUPS script hangs at
The rasterisation stage; and by running the filter pipeline (texttops,
pstops, pstoraster ...) manually I can see that ghostscript segfaults
when called by gstoraster.
Following shows a gstoraster session with a build of gs from ports with
DEBUG and CUPSDEBUG2, followed by a gdb backtrace on the gs core dump
using unstripped versions of gs and libgs.
It looks like cups_set_color_info() is called with one device pointer
(0x8423b034) and then there's a get/put_params() with a different one
(0x882eb034). Is this normal? The second one segfaults when
gsicc_set_device_profile tries to write its icc profile. I'm guessing
there may be a missing call to gsicc_init_device_profile_struct() or
something like that...
I've had a trawl through the patches on git.ghostscript.com since the
release of 9.05, but I can't see anything directly relevant.
Thanks in advance for any help or suggestions.
