testcase
The attached testcase requires a very long compile time with current trunk.
this requires about 35s (+- OK)
gfortran -c -O1 -g hog.f90
this requires > 900s
gfortran -c -O1 -g -fbounds-check hog.f90
(4.6 branch does better with only 57s in the latter case)
The same testcase was discussed (and fixed) in
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=43627
but the issue might be different this time.
