Debugging Dynamic Memory Usage Errors Using HP WDB (5900-1474; WDB 6.2; January 2011)

Example 16 Batch Mode Debugging for a 32-bit Application running on Itanium
Sample Program
$ cat memtest.c
1 #include <stdlib.h>
2 #include <string.h>
3 #include <stdlib.h>
4
5 #include <signal.h>
6 void myhandler(void ) {
7 exit(0);
8 }

10 main(int argc)
11 {
12
13 // signal(11, myhandler);
14
15 char *p[20], buffer[]="0123456789012345", *temp;
16 int i;
17
18 for (i=0; i<20; i++) {
19 p[i]=(char *)malloc(4);
20 };
21 memcpy(p[15], buffer, 12);
22 for (i=0; i<10; i++) {
23 free(p[i]);
24 };
25 free(p[9]);
26 }
