Ubuntu与Red Hat错误

Question

I have a C code which successfully runs under ubuntu, but when I am trying to run it on a red hat PC it is giving a "Segmentation fault (core dumped)" error. I have narrowed down the error to be from the following statement:

long int encryption[800000][2];

this declaration is causing the code to crash.

What can I do? Any suggesstions? cheers =)

Answer 1

Change it to

static long int encryption[800000][2];

Or make it global, or use malloc .

Or use ulimit -s .

Answer 2

You are experiencing a stack overflow because the array is allocated on the stack.

The size of the stack is platform defined, depends on the threading model and configuration, and on sysctl / ulimit settings (among others?).

Make the array dynamically allocated or statically allocated ('global') to prevent this
