The problem is in c-typeck.c (build_unary_op) (around line 2986).
the code looks like:
if (TREE_CODE (arg) == COMPLEX_CST)
return TREE_IMAGPART (arg);
else if (TREE_CODE (TREE_TYPE (arg)) == COMPLEX_TYPE)
return fold_build1 (IMAGPART_EXPR, TREE_TYPE (TREE_TYPE (arg)), arg);
else
return convert (TREE_TYPE (arg), integer_zero_node);
So there is no check for TREE_SIDE_EFFECTS. Maybe it should use
omit_one_operand or build a COMPOUND_EXPR. Either one will fix the
bug.
