Hi,
i am working in C in Fedora Eclipse 3.3.0 with gdb debugger. I am geting segmentation fault with an error message "mi_cmd_var_create: unable to create variable object" on debugging the program.

What should I do to solve this problem?

rgds,

Is this variable local to a function or is it global. If global check the allocated data segment size else check the allocated stack segment. Try increasing the size of whichever segment it lies in.

I tried by increasing the stack size.But it is not working . It is actually stopped due to segmentation fault with a debugger message "suspended: signal 'SIGSEGV' received".

It is declared as global variable. Is it due to some register related problem?

It would help a lot if we could see the code. Does the code compile with no errors and no warnings? .. global variables are not allocated on the stack.

It compile with no errors and no warnings.This is the part of code

#include<stdio.h>
#include<string.h>
#include "header.h"
#include "struct.h"

extern struct stack_rec stack[100];
extern char word[MAXWORD], mal_mean[MAXWORD], E_attr[MAXLEN], H_attr[CATLEN], semantic_tag[MAXWORD];
extern int word_cat, top, VOICE, prep_par, pos, phrase;

void getreltvform (char[], int);
void check_suffix (char[], int , int);
int p = 0;

/***This function is used to resolve the meaning of relative pronouns and takes the formation with the word***/

void resolve_reltvpronoun ()
{
char mmean[MAXWORD], means[5][MAXWORD];
int len = 0, i, clen = 0, ci = 0, spos = 0;

p = pos;
printf ("\ninside resolve rel pronouunnn\n");
if (stack[top - 1].word_cat == KARAK && prep_par == 7)
spos = top - 2;
else
spos = top - 1;

strcpy (mmean, stack[spos].mal);

len = strlen (mmean);
printf ("\n\nstack mal : %s\n", mmean);

stack[spos].mal[0] = '\0';

for (; i < 5; i++)
means[i][0] = '\0';

for (i = 0; mmean[i] != '\0'; i++)
{
if (mmean[i] == '/')
{
means[clen++][ci] = '\0';
ci = 0;
}
else
means[clen][ci++] = mmean[i];
}
means[clen][ci] = '\0';

for (i = 0; i <= clen; i++)
getreltvform (means[i], spos);

stack[spos].mal[strlen (stack[spos].mal) - 1] = '\0';
printf ("\n final stack mallllllllll : %s", stack[spos].mal);
}

segmention fault occur at the line -stack[spos].mal[0] = '\0';If we comment the line it will go to another line after that.
All the extern variables are declared in other files.

Sounds like spos is going out of bounds. Can you print out its value just before? How large is stack[] and how is it defined?
