--- Comment #1 from Dominique d'Humieres <dominiq at lps dot ens.fr> ---
Confirmed on 4.8.2 and a clean 4.9.0, r206033. However the compilation exits
without ICE on my patched tree (r206072) but with the additional error

pr59024.f90:17.14:

END MODULE mtc
              1
Error: Procedure 'C_PTR_1' in generic interface 'tc' at (1) is neither function
nor subroutine

So this PR is likely a duplicate with a known fix. I'll try to figure out the
link.

AFAICT the errors with the trunk (5.0) are now

pr59024.f90:6.6:

  TYPE tc
      1
Error: Syntax error in PUBLIC statement at (1)
pr59024.f90:7.5:

  END TYPE tc
     1
Error: Expecting END MODULE statement at (1)
pr59024.f90:15.12:

    TYPE(tc) t
            1
Error: Derived type 'tc' at (1) is being used before it is defined
pr59024.f90:17.14:

END MODULE mtc
              1
Error: Procedure 'C_PTR_1' in generic interface 'tc' at (1) is neither function
nor subroutine

without any ICE. The change of behavior occurred between revisions r214073
(2014-08-17, ICE) and r214113 (2014-08-18, error). A candidate could be
r214076, but I don't see why.

Unless someone objects I'll close this PR as fixed in a week.

This seems to depend on the mood of my machine:

So the bisection is not accurate, probably for the same reason as for pr59016.
