openssh unix dev - Oct 2001 - segmentation violation using openssh-2.9.9p2 on linux 2.2.19

I received a segmentation violation whilst using openssh-2.2.9p2 today:

	Kernel 2.2.19-6.2.7 (Redhat 6.2)
	Gcc version egcs-2.91.66
	glibc-2.1.3-22
	Hardware is 333MHz K6-3Dnow with 64MB RAM if that matters

Here is what happened along with a stack dump...


# ssh -L 80:someplace.net:80 -l charlie someplace.net

The stack trace looks a little weird - did you compile with debugging
symbols?
