Currently you can't, AFAICT.

Many Linux distros these days make PIE the default for Clang/GCC,
because PIE allows for more ASLR, a common modern security 
hardening
measure.

Because D uses the C compiler to link your application, this 
default
will be passed down to the linker. Because of the order in which D
passes args down to the linker, there doesn't seem to be a way to
override this (unless you link manually, e.g. by appending 
`-no-pie` to
the clang/gcc command you get with `dmd -v <sources>`).

It might make sense to change dmd's behaviour so it explicitly 
passes
`-no-pie` to the C compiler when it's not being called with 
`-fPIC`.

In any case, the bug is still not D's fault and will also occur 
with
e.g. C programs compiled without `-no-pie` (and probably most
executables in /usr/bin!).
