[Bug middle-end/44722] New: [4.6 Regression] Long compile time or infinite loop

[jvdelisle at gcc dot gnu dot org]

gfortran -O2 array_reference_1.f90 just hangs.  I have to go in and kill it
manually.  This is just one example.  There were several failures before I
interrupted make -k check-fortran in order to recover enough CPU cycles to then
go in an kill f951 that was left running.

No problems at -O1 so maybe middle-end?
