Jack> XEmacs does crash when I visit a PNG file, but that doesn't Jack> tell me we've got a faulty library. That makes plenty of sense, but: been there, done that. Upgrading libpng (or perhaps simply rebuilding it with a newer toolchain) has caused crashes on at least Solaris. Rebuild XEmacs, crash goes away in those cases. We've seen the stack traces for those, it is pretty clearly crashing inside of libpng, not in the glue code. Guessing that it's the same for your crash is a bit of a stretch, but this is very stable code (I don't think it has changed since XEmacs 20.4, and it's basically the same in 21.4 and 21.5 as in 21.1), and we know that libpng upgrades caused crashes on other similar platforms.

Well, that's what we're talking about, too. XEmacs was probably built with an older header. When Steve says "dodgy library", what he means is that libpng upgraded in a backwards incompatible way but is still link-compatible. Boom!

Have you rebuilt XEmacs from the port since the most recent upgrade of libpng? You _are_ going to have to rebuild, unless you can get somebody else to do it for you. You cannot possibly solve a crash without rebuilding (except by avoiding use of the "dangerous" feature). -- Institute of Policy and Planning Sciences http://turnbull.sk.tsukuba.ac.jp University of Tsukuba Tennodai 1-1-1 Tsukuba 305-8573 JAPAN Ask not how you can "do" free software business; ask what your business can "do for" free software.
