C - Fclose -> Aborted (core dumped)

I am getting an error of Aborted on fclose want to know where I am doing wrong. Core Duped:

Stack trace:
Frame     Function  Args
0022A698  7C802542  (00000758, 0000EA60, 000000A4, 0022A794)

End of stack trace

I am using Cygwin + GCC + Autotools for the project. Didn't understand what that means. After this point nothing is there as the program has to exit but showing Aborted is disturbing..

One standard way to get a core dump from fclose() is to pass it a file pointer that's null, because you failed to open the file:

 FILE *fp = fopen("/long/hairy/path/with/a/missing/file/at/the/end", "r");

 fclose(fp);

Always check the return value from fopen() and its relatives:

if (fp == NULL)
    ...report problem
else
{
    ...use fp...
    fclose(fp);
}
