Unmatched [/color] tag causes client crash.

Brett Anthony shared this bug ago

Reported

A programmable block script may echo the following which causes a crash.

Echo("[/color][color=#ffaabbcc]");

it seems that generally any closing color tag which is followed at some point by a starting color tag (which may or may not itself be matched with a closing tag), causes an immediate crash to desktop for any clients attempting to view a programmable block which is echoing the given in the terminal. The server itself does not appear to crash, here's the stack trace:
