For example: "GNU GPL v1 only", "GNU GPL v2 or later" or "GNU GPL v3" and so forth.

Heh. Even the LSM spec is vague: http://lsm.qqx.org/LSM.README

Hi Vince/deater,

Thank you for writing ansi2gif, it's a fantastic little program! I've found a case where it crashes, and I thought you might be interested.

This minimal crashing example, escape-left-bracket-m-segfault.ans.txt, contains the terminal escape code ESC[m, which causes ansi2gif to segfault.

ESC[0m is the terminal escape sequence for 'reset graphics mode' or 'reset all color/font attributes'. Unfortulately, some programs instead send Esc[m, with nothing instead of a digit. I'm not sure whether this is also allowed by the standard (which I couldn't find anywhere), but it a search on searchcode.com suggests it is common. Parsing ESC[m without crashing, and interpreting it as ESC[0m, should fix the issue.

I'm afraid I don't know enough of C myself to submit a patch. Please don't feel obliged to fix this, though; and thank you for all your work polishing ansi2gif.

Kind regards,
Sietse

P.s. Because these terminal escape codes are quite hard to google, and because there is huge fragmentation in how they are spelled out, I'd like to put a few variant spellings here so that future googlers can easily find it.

ESC[0m, ESC[m
ESC [ 0 m, ESC [ m
\[[0m, \[[m,
^[[0m, ^[[m
Escape left bracket zero m, Escape left bracket m
Escape bracket zero m, Escape bracket m.
