[Bug tree-optimization/30087] New: regressions in the gfortran testsuite with -ftree-vectorize

[tobi at gcc dot gnu dot org]

Running the gfortran testsuite with "-O2 -ftree-vectorize" started giving a
number of failures in the span of the last 3-4 days.  Namely, the testcases
 gfortran.dg/actual_array_constructor_3.f90
 gfortran.dg/array_constructor_8.f90
now lead to ICEs in the compiler.

This blocks my effort to make the gfortran testsuite run with -ftree-optimize.

Backtrace of the first (second looks similar)

I wonder if this is related to vectorizer testcases failures
(http://gcc.gnu.org/ml/gcc/2006-12/msg00261.html), since this regression
occurred at about the same time.
