ghostscript segfaults on ppc

[Andy Wingo]

I get segfaults doing things with ghostscript on ppc. I'm building gstreamer
0.9, for the record -- these errors show up when building documentation. This is
with Broken^WBreezy Badger ;-)

ps2pdf segfaults converting the first attachment to pdf.
gs segfaults converting an eps file to png (second attachment).

converting fig to png fails

Just running gs segfaults:

0x10099870 in gs_alloc_string_ref ()
(gdb) bt
#0 0x10099870 in gs_alloc_string_ref ()
#1 0x1009a2f8 in gs_gc_reclaim ()
#2 0x100e0270 in gs_image2_t_init ()
#3 0x100e0270 in gs_image2_t_init ()

Rillian suggested it might be a gcc4 bug.

On my Breezy powerpc system both gs-gpl and gs-afpl also segfault. gs-esp is ok.

Ian, can you please take a look at this? Thank you!

I think this was fixed at some point in the breezy cycle. In any case, ps2pdf works fine on that file using gs-gpl 8.15-4ubuntu1 on davis.

If anyone is having difficulty on dapper, would they please file a new report. Thanks.
