I can reproduce it. Seems to be off-by-one here:
Z_STRVAL_P(result) = target = safe_emalloc(char_count, to_len, len);
introduced by this patch:
http://cvs.php.net/viewvc.cgi/php-src/ext/standard/string.c?r1=1.445.2.14.2.36&r2=1.445.2.14.2.37
If I replace len with len+1, it seems to be OK.
Looking more on this code of php_char_to_str_ex, it seems very strange to me, especially this part:
if (char_count == 0 && case_sensitivity) {
ZVAL_STRINGL(result, str, len, 1);
return 0;
}
Why check case_sensitivity here? Looks like some code remained un-cleaned from previous versions. Any arguments against removing this check?
