While I am aware of the differences between debug and release builds, I am curious if attaching the debugger to a process (built release or debug) changes that processes behaviour?
For reference, I’m developing on HP 11.31 Itanium but still am curious for the general case.

Of course, attaching a debugger will change the timing (which can change e.g. thread race conditions), and also some system calls can detect if a debugger is attached.
