I using chilkat library in my C++ program, it compile correctly but while running the program it crash in Linux even it works fine with windows.

I am trying to trace it on valgrind and after execution of some command it shows below error log:

I dont understand. I tried to get some information about ClsBase::logProgrammingLanguage2(LogBase&) but fail. help me.

Maybe the problem has to do with your extremely old version of libc (v2.12). Chilkat provides an older build that uses libc 2.3.4. See the Linux C++ lib downloads at http://www.chilkatsoft.com/chilkatLinux.asp

Also, Chilkat version 9.4.0 was released today, so you might try downloading this new version to see if it makes a difference.
