Re: Illegal instruction when running plmerge or a built app

[Fred Kiefer]

Most likely this is caused by a compiler bug. The code in this function 
looks correct to me, it involves a lot of implicit type cast though and 
most likely one of them goes wrong for you.
We could try to track this down and add more explicit type casts to 
convince your compiler to do things right, but as Eric already pointed 
out, it is best for you to switch to the better supported cairo backend.
