Dear Crazy Sage,
I'm only using libpoppler-qt4.dll to render PDF pages to images, so I
don't think I will concentrate on this error. But, frankly speaking, I tried to
use Windows Task Manager to monitor the memory usage when running my program
(modified "qq27"), it seems fine without memory leaks on Windows 7. I'm not
sure about this or similar effects on XP or Vista. It's just a rough test.
If this causes a big problem on you, maybe MinGW is a workable
alternative. When built by MinGW, no such exceptions occurred.

Hello, cobra.yu.
I solved first problem by using dynamic qt and poppler, but is there
something that can be done about heap exception? I'm planning to open
lots of pdf in my program and it'll be not cool to left such obvious,
but unsolvable memory leak.
