[lldb-dev] ASLR disabled by default - thoughts?

[Greg Clayton]

So your JIT'ed code on the heap will always end up at the same location as well? That is a pretty big gamble.

Source/line breakpoints can just be resolved every time you debug.  Same with symbol breakpoints.  Even absolute address breakpoints can be translated to Module+offset and persist across ASLR.  The only things I can think of off the top of my head are hardware data breakpoints, and printing addresses to log files.  Is there other stuff that is complicated by ASLR?
