...>> I'm having a hard time mapping this output to what I expected from the structure, but that may be my inexperience with gcc internals. For how to fix this, it seems like the problem here is in gfc_conv_array_initializer() (trans-array.c:2905) , where gfc_conv_structure() is called for EXPR_STRUCTURES in an array initializer, even if it should be constant, and gfc_conv_structure() doesn't set the constant_flag of the expression. My first guess is that we might need to either relax the assertion (not sure what problems that would cause), find a way to communicate that the structure is inten...
