source causing ICE
This was discovered when testing leading-edge features from coarrays.
Program f2.f90 is the culprit. Adding -Wall gives no further clues.
Here's the result:
Dans-MacBook-Pro:coarrays dan$ mpif90 -fcoarray=lib f2.f90 -lcaf_mpi
f2.f90:18:0:
LOCK (lock2)
1
internal compiler error: in gfc_get_tree_for_caf_expr, at
fortran/trans-expr.c:1812
f2.f90:18:0: internal compiler error: Abort trap: 6
gfortran: internal compiler error: Abort trap: 6 (program f951)
Please submit a full bug report,
with preprocessed source if appropriate.
