But reload is neither specific to IA-64 nor Fortran, so this is a generic
latent wrong-code bug. Shouldn

Thanks, Jim. Denis and I are working on a patch based on your suggestion to

I've verified that reload-branch works fine on the regression test-case. It
either works with that Alan's obvious reload fix

This seems to be a reload bug, but Alan Modra's patch is correct.
In *.lreg we have:
(insn 577 78 11 2 (set (reg/f:DI 391)
(reg/f:DI 0 ap)) 5 {*movdi_internal} (nil)
