[Bug tree-optimization/37952] New: failure in polyhedron benchmark when ftree-parallelize-loops is enabled

["razya at il dot ibm dot com" <gcc-bugzilla at gcc dot gnu dot org>]

gas_dyn fails when autopar is enabled.
The failure is durig alias computation for one of the new parallel functions
created by autopar.

gas_dyn.f90: In function âcortesa._loopfn.0â:
gas_dyn.f90:1791: internal compiler error: in referenced_var_lookup, at
tree-dfa.c:565
