Thanks. This is here:
while (!char_quoted (pos, pos_byte)
/* Previous statement updates syntax table. */
&& ((c = FETCH_CHAR_AS_MULTIBYTE (pos_byte), SYNTAX (c) == Squote)
|| syntax_prefix_flag_p (c)))
{
opoint = pos;
opoint_byte = pos_byte;
if (pos + 1 > beg)
DEC_BOTH (pos, pos_byte); <<<<<<<<<<<<<<<<<<<<<
}
I don't see how could that crash. Anyone?
