Michael Lundkvist <ml(a)epact.se&gt; writes: [snip backtrace of crash in redisplay ] If I load the file in "Apollo" (on Linux 2.0.35) compiled with-mule (and the default error-checking) I get a crash a bit earlier at file-coding.c:3907, which is: 3904 charset = str->iso2022.charset[reg]; 3905 3906 /* Error checking: */ 3907 if (NILP (charset) || str->iso2022.invalid_designated[reg] 3908 || (((c & 0x7F) == ' ' || (c & 0x7F) == ISO_CODE_DEL) 3909 && XCHARSET_CHARS (charset) == 94)) random debugging stuff follows: (gdb) p str->iso2022 $4 = {charset = {138349840, 138171016, 138170988, 138170988}, register_left = 0, register_right = 1, esc = ISO_ESC_NOTHING, esc_bytes = "\000\000\000\000\000\000\000", esc_bytes_index = 0, composite_chars = 0x0, invalid_designated = "\000\000\000", switched_dir_and_no_valid_charset_yet = 0, invalid_switch_dir = 0, output_literally = 0, output_direction_sequence = 0} (gdb) p reg $5 = 1 Of the four charsets only the first (str->iso2022.charset[0]) seems valid. charset[1] is the Symbol 't' the other two are 'nil'. Maybe one of the mule (or file-coding) people can have a look at this...
