Bug description: mb_get_info causes seg fault
Description:
------------
Calling the mb_get_info() function causes segmentation fault. This
happens both as Apache module and CLI.
The other mb_* functions work fine, it's just the info that causes a
problem.
Compiled with:
'./configure' '--prefix=/usr/local' '--with-apache=../apache'
'--with-mysql=/usr/local/mysql' '--with-curl=/usr/local' '--with-gd'
'--with-mcrypt=/usr/local' '--enable-mbstring' '--with-zlib'
'--with-iconv' '--with-pspell=/usr/local' '--with-curlwrappers'
'--enable-soap' '--with-libxml-dir=/usr/local' '--without-sqlite'
Reproduce code:
---------------
<?php
var_dump(mb_get_info());
?>
Expected result:
----------------
Multi-byte string library info.
Actual result:
--------------
Program received signal SIGSEGV, Segmentation fault.
