You can use hardware watchpoints.

You have to get the address of the variable you want to track (type p &my_var in gdb prompt).

It will print somehting like 0x12345678.

• With gdb: type watch *(int *)0x12345678.

• With lldb: watch set expression (int *)0x12345678 (or w s e (int *)0x12345678)

This assumes your variable is an int. It will create an hardware watchpoint on this address.

Hope this helps.
