FWIW, a tree I got earlier today fails to bootstrap while compiling
libjava/verify.cc on both i686-linux-gnu and x86_64-linux-gnu
(compiling libjava with -m32).  It fails because the upper bound of
arg_types on line 2102 is an ssa_name, and
dwarf2out.c:loc_descriptor_from_tree doesn't know how to handle that.
May I assume this is the same problem that you guys are looking into?
