Hmm, we call gimplify_type_sizes from:
/* ??? We really shouldn't need to gimplify the type of the variable
since it already should have been done. But leave this here
for now to avoid disrupting too many things at once. */
if (!TYPE_SIZES_GIMPLIFIED (TREE_TYPE (decl)))
gimplify_type_sizes (TREE_TYPE (decl), stmt_p);
Here is the backtrace by the way:

I think we are missing a SAVE_EXPR somewhere.
