readers crash when paging from TOC #815

Closed chrox closed 11 years ago

chrox commented 11 years ago

I didn't reproduce this bug in the emulator. But it happened in both pdf reader and epub reader on Kindle. Debug info says 

*** glibc detected *** ./kpdfview: double free or corruption (!prev): 0x00655630 ***

or simply: Segmentation fault.

And more tests show that it crashes much more often in landscape mode than portrait mode. You can reproduce it by opening any pdf documents with TOC information and just selecting several TOC entries. It will crash randomly with these info:

Segmentation fault

or

*** glibc detected *** ./kpdfview: double free or corruption (!prev): 0x00655630 ***

or

*** glibc detected *** ./kpdfview: malloc(): smallbin double linked list corrupted: 0x007084a8 ***

or

kpdfview: malloc.c:4636: _int_malloc: Assertion `victim->bk_nextsize->fd_nextsize == victim' failed.

This bug also exists in kindlepdfviewer-v2012.04.2-676-g72eecac.zip, the very first version we introduced landscape screen mode.
