Getting Segmentation fault

[Rajnikant]

Hello everyone,
 
I'm trying to call 'C' routine from perl script. I have static library
(libFile.a) where I can get object code of 
this routine and I have linked it with my perl script. This perl script get
compile but after running it I'm getting
segmentation fault. See code below for reference:
 
=================== C Routine ==================
#include <stdio.h>
#include <string.h>
 
char *  MyMethod(char *data)
{
   strcpy(data,"My text from C Code ");
   return data;
}
steps to get libFile.a:
cc -c libFile.o libFile.c
ar rcs libFile.a libFile.o
 
=========================== PerlScript ==============
package Caller;
use Inline C => Config =>
                ENABLE => AUTOWRAP,
                LIBS => '-L/lib_location -lFile',
                INC => '-I/lib_location'
              ;
use Inline C => <<'END';
char * MyMethod(char *data);
AV* AVstr;
SV* SVstr1;
void DisplayData()
{
    AVstr=newAV();
   // Call to function defined in library
    AVstr =  MyMethod(AVstr);
    printf("\n SVstr1 data: %s\n",AVstr);
}
END
1;
 
use strict;
# call to Function
   Caller::DisplayData();
1;
Compile: perl -c Script_name
run :  perl -w Script_name
 
Do you have any guess why am I getting Segmentation fault? Is this the right
way to pass parameters and 
particularly memory allocation and deallocation?
 
Thanks in advance.
