I wonder if it's somehow specific to this chromebook. I'm running a thing called "crouton", which gives you a chroot (of sid, in this case, but you can get various other debian/ubuntu releases too). The X server that the terminal program is using will send all its pixels to a Chrome extension that draws them into a web frame. I don't *think* any of that should be visible to the application, but maybe drawing pixels doesn't happen as fast as it would on a normal computer? > In other words, this assertion fails: > http://sources.debian.net/src/vte2.91/0.46.1-1/src/vtestream-file.h/#L790 > > z_ret = uncompress ((Bytef *) dst, &dstlen_ulongf, (const Bytef *) > src, srclen); > g_assert_cmpuint (z_ret, ==, Z_OK); > > Would be great if you could confirm by posting the asserting message > that the application outputs when crashing. I ran lilyterm from a non-crashing terminal (xterm) and had it dump a MB of "a"s, and got: Vte:ERROR:/home/warner/stuff/debian/vte2.91-0.46.1/./src/vtestream-file.h:790:unsigned int _vte_boa_uncompress(char*, unsigned int, const char*, unsigned int): assertion failed (z_ret == Z_OK): (4294967293 == 0) and a coredump. So yes, I think that matches. (I'm using lilyterm because I wasn't able to get gnome-terminal to run from a regular shell.. I assume that it wants to be launched from some special GNOME mode where it gets a control socket or a D-Bus thing or something). > Seems to me like you need to seek the answer to why uncompress fails > in the zlib library....

I don't know much about terminal programs, but from the other symbol names in that stack trace (VteTerminalPrivate::insert_rows, _vte_ring_insert), I wonder if this involves the scrollback history. Toggling lilyterm's "Scrollback lines" option didn't seem to help. I'll keep digging, and I'll file a bug on the gnome tracker. cheers, -Brian
