Title: Segmentation fault in search_component() from libdotgen.so.0
Submitter: Max Alekseyev

Subsys: Dot
Version: 2.2
System: *-*-
Severity: major
Problem:
I run "dot -v -Tpng -o matches.png matches.dot" but it segfaults

Program received signal SIGSEGV, Segmentation fault. 0xb7e07d5c in search_component () from /usr/lib/graphviz/libdotgen.so.0
Input file: b617.dot
Comments:
[erg] search_component is recursive. For the input graph, there are 4106 nodes but in the second pass to decompose, with virtual nodes added, there are 1464096 nodes. Thus, a good guess is that the stack is being blown. In some cases, it may be sufficient to simply use ulimit to raise the available stack size.

Corresponds to Debian bug #292385.

Here is a smaller input.
