Filed on behalf of Ross Alexander; he posted to nautilus-list -


I have the following simple example.

<?xml version="1.0" standalone="yes"?>
<svg width="3100" height="2200">
<g style="stroke-width: 4pt;">
<rect x="0" y="0" width="310" height="220" style="fill:pink;"/>
</g>
</svg>

This works on linux, but only by luck.  On HP-UX it goes into infinite
loops.  Below is a trace from gdb.

what is the value of n_segs and th_arc at rsvg-path.c:153 on your hpux
machine
Comment 3 Ross Alexander 2003-03-14 14:53:37 UTC 
(gdb) print n_segs
$3 = 2147483647
(gdb) print th_arc
$4 = nan(0x4000000000000)
Comment 4 Dominic Lachowicz 2003-03-14 15:36:52 UTC
