I'm trying to debug a binary that uses a lot of pointers. Sometimes for seeing output quickly to figure out errors, I print out the address of objects and their corresponding values, however, the object addresses are randomized and this defeats the purpose of this quick check up. Is there a way to disable this temporarily/permanently so that I get the same values every time I run the program.

Disable ASLR If you just want to test for a single program you can use the setarch command. This leverages a so-called personality flag. The -R option disables the randomization of the virtual address space by turning on ADDR_NO_RANDOMIZE. This option allows programs to disable ASLR and run without any randomization.
randomize_va_space = 0 This will permanently disable ASLR.
On Ubuntu , it can be disabled with...
echo 0 > /proc/sys/kernel/randomize_va_space On Windows, this post might be of some help...

To temporarily disable ASLR for a particular program you can always issue the following (no need for sudo)
setarch `uname -m` -R ./yourProgram If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
