Title
Body
I am using Debian squeeze and have noticed that memory is always zeroed. Is this new in linux distributions ? Some time ago, I believe I could use puts() and garbage would be output. I run this test program many times but the commented results are always the same. (I have randomize_va_space=2 in sysctl.conf so I know that memory in different locations is being used at each run.) char *a = malloc(50000000); a[49999999] = '\0'; puts(a); // it outputs nothing since all are zeroes printf("%p\n", a); if(a[5000] == '\0') // this condition is always true { puts("It is a nul char."); } Is it possible to make the system not zero memory ? What options could this Debian squeeze installation have activated that always zero memory ?
