Hi again: I've become frustrated with trying to install a recent
pango/cairo under CentOS 5.8--too many dependencies.
So, in trying to debug the segfault, I've found that:
./x01c -dev pngcairo -o foo.png
finally dies beyond tracing (in the plplot code, anyway) at:
line 289 of plcore:
289 ( *plsc->dispatch_table->pl_esc )( (struct PLStream_struct *) plsc, op, ptr
);
(see attached stack trace).
The function pointer called was in cairo code (I think):
(gdb) p *plsc->dispatch_table->pl_esc
$20 = {void (struct PLStream_struct *, PLINT, void *)} 0x2aaaabd71087
<plD_esc_cairo>
The program was just in the process of drawing an axis label (the number
'1') deep within plbox.
Any ideas what I can do here short of upgrading my entire OS?
Thanks,
Doug

Hi all: I'm just now upgrading to plplot 5.9.9 in my CentOS 5.8
environment. This OS features old pango/cairo versions:
pango-1.14.9-8.el5.centos.3
pango-devel-1.14.9-8.el5.centos.3
cairo-1.2.4-5.el5
cairo-devel-1.2.4-5.el5
When I run example 1 with any of the cairo devices, I get a segfault:
[rpmbuild@fox c]$ ./x01c -dev pngcairo -o foo.png
PLplot library version: 5.9.9
Segmentation fault
Other device drivers work fine.
Has anyone seen this? If not, I'll start debugging and/or trying to
upgrade to a more recent pango/cairo.

Doug
