Nope.  Still not getting that failure.  Though after updating I am
getting a failure in libjava:

/fuel98/export/virgin/libjava/ error: Statement marked for
throw, but doesn't.
#   VUSE <D.15186_67(ab)>;
D.28047_69 = D.15186;

/fuel98/export/virgin/libjava/ internal compiler error:
verify_stmts failed.

Can you send me your .ii file and I'll see if I can make it fail.

Based on the information you've provided so far we must have done a
ADDR_EXPR substitution into an INDIRECT_REF which did not fold away
the ADDR_EXPR and INDIRECT_REF for one reason or another.  I can't
immediately think of what would cause a failure to fold, but I'll
poke around and see if anything looks interesting.  At the worst
fixing this just means using a little more memory so that we can
undo the propagation if folding fails.
