Properly terminate symbol inline location data.

Browse Source 
Previously there was no end value on which iteration would stop in case of
the last-in-the-process-space symbol, which resulted in out-of-bounds read.

Workaround has been added for versions < 0.7.2, but no version bump has been
performed (still at 0.7.1). Having two terminator values at the end of the
list is harmless.
