[AC21.5R21.4] fix for off-by-one bug in mule-ccl.c, XEmacs 21.4 and 21.5

The following patch fixes an off-by-one error in the 21.4.21 mule-ccl.c file, which causes corruption and crashes when a ccl program accesses the last official 2D charset, namely chinese-cns11643-2. (This bug has been annoying me for a long time, since I tried to have cns high in the unicode translation precedence list, but couldn't, since I got crashes, which I wrongly assumed to be due to bugs in the code conversion ccl programs. Quite by chance, while trying to track a quite different problem, I noticed this error; fixing it resolves my problems with cns.) This patch should also be applied to the 21.5 source, where the bug is still present. --- src/mule-ccl.c-orig 2008-10-25 16:36:30.000000000 +0100 +++ src/mule-ccl.c 2008-10-25 16:19:31.000000000 +0100 ＠＠ -1380,7 +1380,7 ＠＠ if (XCHARSET_DIMENSION (CHARSET_BY_LEADING_BYTE (i)) == 1) i = (((i - FIELD2_TO_OFFICIAL_LEADING_BYTE) << 7) | (reg[rrr] & 0x7F)); - else if (i < MAX_LEADING_BYTE_OFFICIAL_2) + else if (i <= MAX_LEADING_BYTE_OFFICIAL_2) i = ((i - FIELD1_TO_OFFICIAL_LEADING_BYTE) << 14) | reg[rrr]; else -- The University of Edinburgh is a charitable body, registered in Scotland, with registration number SC005336. _______________________________________________ XEmacs-Patches mailing list XEmacs-Patches(a)xemacs.org http://calypso.tux.org/cgi-bin/mailman/listinfo/xemacs-patches
