At revision 135707, 13 tests (out of 16) of the polyhedron testsuite
(exceptions: gas_dyn, linpk, and nf) fail with options-ftree-loop-linear and
-O1 and above:
[ibook-dhum] lin/test% gfc -w -O1 -ftree-loop-linear tfft.f90
tfft.f90: In function 'rfft':
tfft.f90:152: internal compiler error: in calculate_allocation, at vec.c:51
They worked with revision 135656.
