This is very strange. I wrote a program to test new/delete - 
malloc/free functions. Both sets worked fine as long as 
I “compiled”  the program as a single module. When I built them 
as a project, however, free and delete wouldn’t do 
anything . . . no errors or warnings or anything, but they just 
wouldn’t do anything. I tried all the platforms, but still they 
just wouldn’t do anything. What’s going on?
---------------------------------------------------

/* free example */

#include <string.h>
#include <stdio.h>
#include <alloc.h>
#include <conio.h>
#include <stdlib.h>

int main(void)
{
   char *str;
   	int sub;
   char *myarray[10]= {'\0'};
   char *str1, *str2, *str4, *str3, *str5;
   char line[30], line2[30], line3[30], line4[30], line5[30];

clrscr();

   /* allocate memory for string */
   str = (char *) malloc(10);

   /* copy "Hello" to string */
   strcpy(str, "Hello");

   /* display string */
   printf("String is %s\n", str);

   /* free memory */
   free(str);

   printf("String is %s\n", str);

//-----------------------------

   str1 = new char(30); //(char *) malloc(30);
   strcpy( str1, "linenumber2" );
printf( "1) %s \r\n" , str1 );
    delete str1; //free(str1);
printf( "1) %s \r\n" , str1 );

   return 0;
}
