I've hit the following warning after I've tried to link Firofox's libxul

killed the process after it used all the memory and 90% of my swap
space. Before the machine was rebooted I saw these messages:

BTW, I'm not the only one that sees these messages. Here are two more
reports from Ubuntu beta testers:

The pattern seem to be:

... idx:2 val:x
for x=1,2,14
Ok, thanks. I'll try to figure out how this is happened.
