Bug description: Segmentation fault in ext/ming when adding text without
setting size before
Description:
------------
Calling addString on a SWFText object without setting height or font
before causes a segmentation fault in libming.so.
If only the height is set, the expected error occurs.
Backtrace:
(gdb) bt

at /home/kore/bin/php/php-5.2-stable/php-src/ext/ming/ming.c:3541
... (Complete backtrace on request)
Tested with
PHP 5.1.6, ming 0.3
PHP 5.2-RC5 ming 0.3
Reproduce code:
---------------
<?php
$text = 'Teststring';
$size = 60;
$t = new SWFText();
//$t->setHeight( $size );
//$t->setFont( new SWFFont( 'fdb_font.fdb' ) );
$t->addString( $text );
Expected result:
----------------
Error message like this:
Catchable fatal error: SWFText::addString(): font must be set before
calling addString in /home/kore/devel/ezcomponents/trunk/test.php on line
