Hi! I see a couple of core dumps, when running xemacs (-nw) in an xterm. This one happened while opening an article in gnus: Generating summary...doneFatal error: assertion failed, file glyphs.c, line 3810, !UNBOUNDP (image_instance) Only C-Trace which reads #0 0x1846b3d0 in kill () from /usr/lib/libc.so.3 #1 0x80b38b3 in fatal_error_signal () #2 0xbfbfdfdc in ??
