There are loadable sections in an ELF debug-only file; they all have
type NOBITS instead of PROGBITS, but are otherwise unchanged. I'm
going to make a wild guess here that says you can't do that in
PE-COFF, so the text section is actually missing. So probably we
should figure out whether we're loading a debug-info-only file at this
point, and not issue those warnings. Or else remove the warnings
entirely.

The redirection to /dev/null is silly and should go away, by the way,
so relying on it isn't the right fix. I don't remember if my recently
posted WIP patch removed it. I think it did for most but not all
cases.
