I think I am going to have to go back to the "trans" for the allocate > which should have the length resolved and stuff it into the sym. In trans-stmt.c (gfc_trans_allocate (gfc_code * code)) I find: (gdb) p *code->ext->alloc.ts.u.cl.length.value.integer._mp_d $41 = 10 So it is there and there is code to handle it in that function. However, I do not yet understand the inner workings of frontend to see what the problem is.
