Segmentation fault Core dumped on virtual machine

In a function, I created the following char array.

char key1[500]="";

I am looping through index "i" in the function and copying values of inputFileArray which is a global variable through an index initialIndex (a global index).

key1[i++]= inputFileArray[initialIndex++];

This statement is resulting in error Segmentation Fault(core dumped) when I run.

BTW, this worked fine on another machine in which I compiled using visual studio c++ editor. I get this error when I try to run this on a ubuntu 13.10 on virtual machine. Appreciate your answers.

Learn to use a debugger (usually GDB on Linux). You may want to start here.

Run your program under debugger, and verify that i < 500 and that
initialIndex < sizeof(inputFileArray).

Yes, bugs are often like that: code that works fine (appears to work fine) on one machine crashes on the next.
