Regression testing finished faster than I thought. Doing

=== gfortran Summary ===
# of expected passes 8
# of unexpected failures 4
The first failure in the gfortran.log file is
CFI_address: subscripts[0], is out of bounds. dv->dim[0].extent = 3
subscripts[0] = 3.
CFI_address: subscripts[0], is out of bounds. dv->dim[0].extent = 3
subscripts[0] = -1.
CFI_address: base address of C Descriptor must not be NULL.
CFI_deallocate: Base address is already NULL.
CFI_deallocate: C Descriptor must describe a pointer or allocatable object.
CFI_allocate: Base address of C descriptor must be NULL.
CFI_allocate: The object of the C descriptor must be a pointer or allocatable
variable.
CFI_establish: Rank must be between 0 and 15, 0 < rank (0 !< 16).
CFI_establish: If the C Descriptor represents an allocatable variable
(dv->attribute = 1), its base address must be NULL (dv->base_addr = NULL).
CFI_establish: If base address is not NULL (base_addr != NULL), the established
C descriptor is for a nonallocatable entity (attribute != 1).
CFI_is_contiguous: Base address of C Descriptor is already NULL.
CFI_is_contiguous: C Descriptor must describe an array (0 < dv->rank = 0).
CFI_section: Base address of source must not be NULL.
CFI_section: Source must describe an array (0 < source->rank, 0 !< 0).
CFI_section: Rank of result must be equal to the rank of source minus the
number of zeros in strides (result->rank = source->rank - zero_count, 1 != 1 -
1).
CFI_section: Lower bounds must be within the bounds of the fortran array
(source->dim[0].lower_bound <= lower_bounds[0] <= source->dim[0].lower_bound +
source->dim[0].extent - 1, 0 <= -1 <= 99).
CFI_section: Lower bounds must be within the bounds of the fortran array
(source->dim[0].lower_bound <= lower_bo
unds[0] <= source->dim[0].lower_bound + source->dim[0].extent - 1, 0 <= 100 <=
99).
Program received signal SIGSEGV: Segmentation fault - invalid memory reference.

The 2nd, 3rd, and 4th failures are
