memory allocation error

[prakash0104]

hi every one
i have a problem with memory overlap for malloced struct.
I am trying to load dictionaries but,, after loading them i found that they have some problem

here is the example

seg.c
================

typedef struct 
   {
       char word[30];
       char pos[3];
   }wordList;

wordList *epatterns1=NULL;
wordList *auxillary1=NULL;
int p_size=0,e_size=0,a_size=0;


load_dict(wordList **list1,char * filename,int *size){
	FILE * fp;
	char * pch;
	wordList *list=NULL;
	char temp_line[40];
	unsigned int nrows=0;                   /* number of data rows in the file */
        unsigned int comment=0;                 /* number of comment lines in file */
        unsigned int i=0;                           /* counters */

	fp = fopen( filename, "r");
	if (fp == NULL)
	{
			printf("\nError, file not found\n");
	}
	else
	{
	// Process & close file
	/* count the number of comment lines, and data lines */
        while (fgets(temp_line,sizeof(temp_line),fp)!=NULL) {
                if (temp_line[0]=='#') {
                        comment++;
                } else {
                        nrows++;
                }
        }

        /* allocate string array to write all the lines from the file */
	*size=comment+nrows;
	list = malloc((*size)*sizeof(struct wordList*));
	if (list==NULL) {
                printf("\nCould not allocate  pointer array");
        }

	i=0;
        rewind(fp);
	memset(temp_line, 0, 30);
        while (fgets(temp_line,sizeof(temp_line),fp)!=NULL) {
		pch=strchr(temp_line,'\t');
		strcpy(list[i].pos,pch+1);
		list[i].pos[strlen(pch)-2]='\0';
		strncpy (list[i].word,temp_line,pch-temp_line+1);
		list[i].word[pch-temp_line]='\0';
		i++;
		memset(temp_line, 0, 30);
        }
	fclose(fp);
	}
	*list1=list;
}

main(argc, argv)
int argc;
char **argv;
{
	load_dict(&epatterns1,"epatterns.dict",&e_size);	
	load_dict(&auxillary1,"auxilllary.dict",&a_size);

	int i;
  	for (i=0; i<e_size; i++) {
	  printf("%s\t%s\n", epatterns1[i].word,epatterns1[i].pos);
	 }

}

===========
epatterns.dict

able JJ
al JJ
ance N
ate V
ation N
cy N

auxilllary.dict

am AV
are AV
be AV
been AV
can AV

when i try to print the ausillary dict stored in the wordList struct
program outputs

able
m V
re V
e V
een V
an V


please help... why this problem happened

thanks in advance

> list = malloc((*size)*sizeof(struct wordList*));
You want the size of a wordList, not a pointer to a wordlist

> main(argc, argv)
> int argc;
> char **argv;
This syntax is archaic. How old is the book you're reading?

> memset(temp_line, 0, 30);
a) it's the wrong size
b) it serves no purpose, as fgets always adds a \0 anyway.

> strcpy(list[i].pos,pch+1);
This will also copy a \n, thus blowing away the length of your small array, and trashing something else.
Consider strncpy(), or removing the \n (see the FAQ)
