-----------------------------+----------------------------------------------
Reporter: carlohamalainen | Owner: boothby
Type: enhancement | Status: new
Priority: minor | Milestone: sage-3.4.1
Component: graph theory | Keywords:

Comment(by boothby):
OOps.
{{{
sage: g = Graph()
sage: c = 0
sage: for h in graph_coloring.all_graph_colorings(g,0,False): c+=1
------------------------------------------------------------
Unhandled SIGSEGV: A segmentation fault occured in SAGE.
This probably occured because a *compiled* component
of SAGE has a bug in it (typically accessing invalid memory)
or is not properly wrapped with _sig_on, _sig_off.
You might want to run SAGE under gdb with 'sage -gdb' to debug this.
SAGE will now terminate (sorry).
