	The debugger requires non-shareable copies of text (executable,
shared libraries, etc.) in order to set breakpoints.  The copies may shift
the data layout of the process.

	Even without the debugger involvement, the address-based hash
prevents deterministically repeatable behavior from GCC if the storage
layout of the executable is changed by relinking.
