This is in gimplify_cond_expr on line 1972 in gimplify.c.
Maybe someone else will know what is going on.
Here is what arg is when passed to invert_thruthvalue:
See that it is a integer_type and not a boolean_type so something needs to

Why isn't the call to gimple_boolify earlier in the function working?

I do not know but I can reduce the source to: union tree_node; typedef union tree_node *tree; typedef enum fallback_t { fb_none = 0, fb_rvalue=1, fb_lvalue=2, fb_either=1|2 } fallback_t; int gimplify_expr (tree *expr_p, fallback_t fallback) { tree internal_post = (tree) ((void *)0); if ((fallback & fb_rvalue) && is_gimple_rhs (*expr_p)) { f_temp_2(); } else { abort(); } return 1; }
