Description Adrian Johnson 2010-10-15 05:17:34 UTC

The attached PDF appears to have an infinite loop in TextOutputDev when using the cairo backend. A git bisect shows the commit that introduced this bug to be:

Not a cairo problem, pdftotext exhibits the same behaviour (Adobe Reader does the same btw), the file seems to have a huge amount of whitespace that just confuses the hell out of the code that "sorts" teh characters

Comment 3 Albert Astals Cid 2011-03-30 11:21:26 UTC

It's not an infinite loop either, it's just that the code is bad and takes forever to run (i.e. it should eventually finish)

Comment 4 Brad Hards 2011-03-30 13:43:46 UTC

I guess "forever" is a figure of speech in this context: It will take a long time, but will complete.

Comment 5 Albert Astals Cid 2011-03-30 13:59:05 UTC

Yeah Brad is right :D, sorry about saying it is not infinite and then saying it runs forever :D
