Repeatable panic in current, cause Netscape
Hello The latest -current system crashes while starting up Netscape, mine version is 4.61, Linux one. It's fully repeatable in my case.

excellent, using kgbd, can you please type "up" until you hit
frame 5 and print the value of the ndp and some of the other
variables? A listing of the code at that location would also
be great. ('list')
Sorry I don't know anything about debugging, so I did some
trial-and-error game and used print on something which seemed emit
useful information. Useful from my point of view ;-) Hope it's really
useful. Otherwise please give exact guidelines or I can try limit memory
and get 32MB dump or so suitable for downloading.

Quick look at /usr/sup/src-all/checkouts.cvs:. gives me the 26'th. I must have done cvsup for src-all by accident. Sorry for false alert, my Netscape works now as usual.
