当待翻译字符串包含某些特殊字符时，会导致返回502异常

见 https://github.com/NauxLiu/opencc4php/issues/24 ，为什么关了？是不是问题不予解决？需要其他的日志信息？或者别的？

没有足够的信息，如果你有类似的情况，并且php coredump，请上传一下core文件的函数调用栈. thx

php版本：PHP 7.0.18 (cli) (built: Oct 24 2017 17:46:37) ( NTS )，安装了xdebug等插件 测试代码 :

<?php
$opencc = opencc_open('config' . DIRECTORY_SEPARATOR . 's2t.json');
opencc_convert(urldecode('%E8'), $opencc);

注意:只有简体转换为繁体时，会出现这个问题

我build了php7.0.18, 并且使用了xdebug2.5.5 在centos6.3上未遇到相同的问题

如果可以的话，麻烦将core文件发送给我邮箱一下pkujhd@gmail.com

仍没有复现问题， 另外我看下一下奔溃栈 # 1 0x00007f2dc449dfaa in zif_opencc_convert (execute_data=, return_value=0x7f2dcb2130d0) at /srv/source/php-ext-opencc4php/opencc.c:174 这个地方的代码 168 #if PHP_MAJOR_VERSION < 7 169 char str = NULL; 170 int str_len; 171 if (zend_parse_parameters(ZEND_NUM_ARGS() TSRMLS_CC, "sr", &str, &str_len, &zod) == FAILURE) { 172 return; 173 } 174 od = (opencc_t)zod->value.lval; 175 176 outstr = opencc_convert_utf8(od, str, -1); 177 178 int len = strlen(outstr); 179 180 char rs = emalloc(sizeof(char) * (len + 1)); 181 strncpy(rs, outstr, len + 1); 182 opencc_convert_utf8_free(outstr); 183 184 RETURN_STRINGL(rs, len, 0); 185 #else 只有在php5的时候才会被调用.

是否你的什么配置存在问题
