There's another similar regression that appears to be because of the same bug:
FAIL: gfortran.dg/widechar_intrinsics_10.f90 -O1 (internal compiler error)
FAIL: gfortran.dg/widechar_intrinsics_10.f90 -O1 (test for excess errors)
WARNING: gfortran.dg/widechar_intrinsics_10.f90 -O1 compilation failed to
produce executable
with gdb saying:
