executable causing core
Hi,
One of my executables is coring. I tried to debug the core using gdb. I got the following stack trace:-
gdb reconProcess core

From the stack trace, it seems that there is a problem in the stradd function where it makes a call to malloc(). The following is the code for function stradd():-
/*CODE - stradd()*/
// This funciton adds src to dest
void stradd( char **dest, const char *src )
{
char *tmp;
if( src == NULL )
return;
if( *dest == NULL )
{
tmp = (char *)[b]malloc[/b]( strlen( src ) + 1 );
strcpy( tmp, src );
}
else
{
tmp = (char *)malloc( strlen( *dest ) + strlen( src ) + 1 );
strcpy( tmp, *dest );
strcat( tmp, src );
free(*dest);
}
*dest = tmp;
}
The Highlighted malloc call seems to be giving a problem.
Could anyone help me out.
Thanks in Advance.
