Test case

WebKit eats a huge amount of memory if we are trying to load texts with really large font-size. E.g.: the following test uses all the 8G of my memory and the only solution to kill the browser is a complete PC reboot:


&lt;style type=&quot;text/css&quot;&gt;
		
	* {
	font-size:5388%;

	}
	
&lt;/style&gt;
A

I&apos;ve run the test on release and debug EFL builds, but I&apos;m not sure that it is a port specific issue or not. It would be great if someone could validate it on other ports too.</thetext>

&gt; I tried it with Safari and ToT WebKit, it managed 
&gt; to paint the huge &quot;A&quot; properly without any problem.

Thanks Ossy. Could someone try it on a GTK build too?</thetext>

    <thetext>I guess this bug and the time-out at fast/css/font-size-nan.svg happen for the same reason.</thetext>

    <thetext>I&apos;ve tried the test on a GTK build and it works fine.</thetext>

    <thetext>Closing this bug because the EFL port has been removed from trunk.

If you feel this bug applies to a different upstream WebKit port and was closed in error, please either update the title and reopen the bug, or leave a comment to request this.</thetext>
