[Bug fortran/42207] [OOP] Compile-time errors on typed allocation and pointer function result assignment

Janus,

Although the new reduced case compiles fine in 64-bit mode, I run into linking
problems as soon as I add "program main;  end program" to the end of it:

Undefined symbols:
  "_vtab$bar.1550", referenced from:
      ___m_MOD_new_bar in ccQEi2ET.o
ld: symbol(s) not found
collect2: ld returned 1 exit status

Looking back through my e-mails, I see that you told me on 11/21 that Paul's
TBP patch had not yet been applied to the branch or the trunk. From the above
results, I assume that's still the case.
