You'll see this on x86 too if you use -gdwarf-2 -g1 to compile.  I
suppose since x86 uses stabs by default, this has gone mostly unnoticed.

After considerable debugging it doesn't really appear dwarf2out.c is
misbehaving at all.  I'd like to eventually look closely at how gcj
emits debug info vs. other frontends.  In the meantime, we have this
annoying bug on the branch.

Any ideas on a quick fix for 3.0?  Perhaps the java driver can simply
avoid -g1 altogether?  Neither -g0 nor -g2 exhibit the problem.
