I assume the segv was caused by an uninitialized integer_minus_one_node?
It appears that tree.c:build_common_tree_nodes_2 (and thus the
initialization of integer_minus_one_node) is only called in c-common.c.
So jc1 isn't setting it.  Boom.

My bootstrap/testsuite run prior to installation didn't detect this
because java doesn't appear to be built and tested by default in a
solaris2 bootstrap.  (At least that's what happens for me.  Dunno why.
Is that expected these days or should I investigate?)  In any case,
sorry for the regression.

So... the solution would be to revert the stmt.c change, or initialize
integer_minus_one_node in jc1.  What do you prefer?
