I know 4.x is outdated and all that, and soon to be unsupported
(probably very much unsupported already) but I thought I'd post anyway.

I just got this panic while copying an old website to a new folder via

then trying to use 'vi' over ssh to edit apache config file. It seemed
to panic as soon as I hit enter for the vi command.

Also, I have no idea what those \^@ characters are after the dump. I
have had random garbage printed out after dumping on the last two panics
