Do you have a stack trace?

That depends on what you mean by "caused".  It might not crash unless
compiled with -O3; however, the underlying cause might be an Ethereal
bug that, when Ethereal is compiled with a lower level of optimization,
doesn't cause a crash because the generated code is different - but
might cause other symptoms, such as bad packet dissection.
