#25669 [NEW]: eregi() vs. 8-bit chars in regex

[svs at ropnet dot ru]

Bug description:  eregi() vs. 8-bit chars in regex

Description:
------------
Even though locale is set up correctly, eregi() fails to match
international characters case-insensitively.  The reason, as far
as I understand, is that code in regex/ passes a negative value to
isalpha(). This can be worked around by recompiling regex/regcomp.c
manually with -funsigned-char (assuming GCC is the compiler).


Reproduce code:
---------------
<?php
setlocale(LC_ALL, "ru_RU.KOI8-R"); 
echo setlocale(LC_ALL, ""), "\n";
if (eregi("&#1103;", "&#1071;&#1071;")) { echo "ok\n"; } else { echo
"bad\n";}
if (preg_match("/&#1103;/i", "&#1071;&#1071;")) { echo "ok\n"; } else {
echo "bad\n";}
?>


Expected result:
----------------
ru_RU.KOI8-R
ok
ok


Actual result:
--------------
ru_RU.KOI8-R
bad
ok
