Test file for memory leak detection

Hello,

We are using version poppler-0.10.1. Memory leak exist at 'Page' destruction.
'Dict' objects are not freed.
The following call stack shows memory leak:

==10949== 757 (200 direct, 557 indirect) bytes in 10 blocks are definitely lost
in loss record 846 of 1,162
==10949==    at 0x401DB31: operator new(unsigned) (vg_replace_malloc.c:163)
