Summary0000805: Segmentation fault in search_component() from libdotgen.so.0
Description



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
Additional Information

[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.
