[Bug fortran/41278] New: internal compiler error related to matmul and transpose

[cmklaij at hetnet dot nl]

This works with g95 and ifort but gives a compiler error with gfortran:

bash-3.1$ cat bug.F90 
program bug

  implicit none
  real, dimension(3,3) :: matA,matB

  matA(1,:)=(/1., 2., 3./)
  matA(2,:)=(/4., 5., 6./)
  matA(3,:)=(/7., 8., 9./)

  matB=matmul(transpose(0.5*matA),matA)

end program bug
bash-3.1$ gfortran -v -Wall bug.F90 -o bug
