After devision, cpu can't run normal code

I am using YAGARTO Tool to compile code for AT91SAM7X512 CPU. In which it
provides ECLIPSE as editor and GCC Version 4.2.1 as compiler. When i
compile my project it code space around 256776 Bytes and used ram around
32480 Bytes. It works ok. Now as i add other .C & .H files, my code stop
working. I m not calling any function of last added files. Just i only put
those files and compile and link. But i m not using any fucntion out of
those file. After adding these .C & .H files my code size becomes around
353212 Bytes and used ram size around 66108 Bytes.
When i debug code i found that whenever it find devision operation it goes
somewhere else and not executing remaining program. So, i m not able
understand why this happen. I add only .C & .H files, which are not used
any where in my Project. I need those files, but currently i just added
those files. My code compile ok but not able to run after devision
operation.

Add -ffunction-sections -fdata-sections to your compiler flags 
and --gc-sections to the linker options.  This should remove any unused code 
from the binary.

Are you sure you are not using an AT91SAM7X256 (or have linking set up 
for that device)?  The devices are pretty much identical except for the 
memory sizes, and your code has trouble once you've passed the limits 
for the 256k device.

I notice you are mentioning .C and .H files.  These (uppercase)
file extensions indicate to the compiler that it is dealing with
C++ code.  Rename the files properly to lower case if they are C
code.
