Yeah,i got okular's source from git today.
The old version seems don't have this bug.
Comment 3 Albert Astals Cid 2011-09-28 13:31:47 UTC 
Can you post a valgrind trace?
valgrind okular myfile.chm

Okular crashed when chm file is more larger.That chm file cause okular crash is 13.5M.For small chm file such as 300K,okular doesn't crash.

This is valgrind okular large_file.chm 's output:

Did it crash when running thorugh valgrind? The log seems to indicate it did not

No,it doesn't crash thorugh valgrind.
But for the same file,it doesn't run throught valgrind,okular crash every time.

Works fine here when using file with md5sum
4fd80c7f20fba9ca03e00d06be39570c  C++ GUI Programming with Qt 4, Second Edition.chm

Are you closing Okular after or before the first page is displayed?

I close Okular after the first page is displayed.I alse viewed the file for some time.
I alse tried some other chm file ,one file 13.5M (crahed),one file 8.6M(crahed),one file 2.2M(doesn't crash).
I removed all config-related file in .kde,the result is the same.
Comment 9 Albert Astals Cid 2011-09-28 20:55:00 UTC 
Without being able to reproduce it and valgrind giving no info about it, it is quite difficult or almost impossible to think, also your build seems to be somewhat broken since there are things like

#18 0x03de21f8 in Okular::Part::~Part (this=0x825f438, __in_chrg=<value
optimized out>, __vtt_parm=<value optimized out>) at
/home/uli/bin/kde4/okular/part.cpp:655
#19 0x03de2272 in Okular::Part::~Part (this=0x825f438, __in_chrg=<value
optimized out>, __vtt_parm=<value optimized out>) at
/home/uli/bin/kde4/okular/part.cpp:680

In the backtrace implying that part.cpp line 680 calls line 655 of part.cpp which is totally impossible.

Which compile options do you use for compiling okular?

just 
cmake .. -DCMAKE_INSTALL_PREFIX=$(kde4-config --prefix)
make
sudo  make install
Comment 11 Fabio D'Urso 2014-05-08 14:16:23 UTC 
Can you try with Okular >= 0.19.0 (KDE >= 4.13.0), can you still reproduce this issue?
Thanks for caring about Okular :)
