I believe this has been introduced by

http://gcc.gnu.org/viewcvs?root=gcc&view=rev&rev=158274

aka

http://gcc.gnu.org/ml/gcc-patches/2010-04/msg00627.html

change, particularly fold_binary_op_with_conditional_arg part of the patch.

arg is not constant, doesn't have TREE_SIDE_EFFECTS, but is a huge expression

with lots of COND_EXPRs in it, nested.
