Summary0000909: dot crashes on labelled edges
Description



I'm composing the state machine for decoding RC5 infra-red
remote control signals. dot crashed on the graph until
I commented out some edge labels.
Steps To Reproduce

digraph rc5
{
rankdir=LR;
{rank=same;last1;11;}
{rank=same;timeout;idle;measure;}
{rank=same;last0;00;}
timeout[shape=box];
idle[label="idle\ntimer 0\n?low"];
measure[label="measure\ntimer 1.2MHz/64\n?high"];
{rank=same;last1[label="last1\n?low\n!1"];last0[label="last0\n?low\n!0"];}
11[label="11\n?high"];00[label="00\n?low"];

timeout->idle;

#blue=low, red=high
idle->measure[color=blue];
measure->last1[color=red];

last1->last0[color=blue/*,label="3/4T..5/4T"*/];
last1->11[color=blue/*,label="1/4T..3/4T"*/];
11->last1[color=red/*,label="..5/4T"*/];

last0->last1[color=red/*,label="3/4T..5/4T"*/];
last0->00[color=red/*,label="1/4T..3/4T"*/];
00->last0[color=blue/*,label="..5/4T"*/];

# timing errors
last1->idle[color=blue,label="..1/4T,5/4T.."];
11->idle[color=red,label="5/4T.."];
last0->idle[color=red,label="..1/4T,5/4T.."];
00->idle[color=blue,label="5/4T.."];
}
Additional Information

Remove the /* and */ in the graph to get a crash (SIGSEGV). I haven't
compiled from the sources, so here is an incomplete stack trace:
<CD>
#0 0xb7e15fd5 in dot_splines () from /usr/lib/graphviz/libdotgen.so.0
0000001 0xb7e15776 in dot_splines () from /usr/lib/graphviz/libdotgen.so.0
0000002 0xb7e0d12a in dot_layout () from /usr/lib/graphviz/libdotgen.so.0
</CD>

This might be a duplicate of bug 716.
