The following will crash the kernel in Mathematica 8:

VertexDelete[AdjacencyGraph@AdjacencyMatrix@Graph[{1 -> 2}], {1, 2}]

AdjacencyGraph@AdjacencyMatrix@ part is to create in internal
SparseArray representation.

Can anyone confirm the crash?

yes, just tried 8.0.0 and 8.0.1 on Windows XP, you might want to file a
bug report...

cheers

Confirmed and reported. Thanks,

On Mathematica 8.0.1 for Linux (just picked it up this morning!), it crashes
the kernel.

Confirmed for Mathematica 8.01. The Kernel exits but the frontEnd
remains running.

In[1]:= $Version

Out[1]= "8.0 for Mac OS X x86 (64-bit) (February 23, 2011)"

Send in a bug report to sup...@wolfram.com (but John Fultz will also
read this and probably file a report :-) hi John! )
