I tried to install the flang-new compiler from Homebrew on Sequoia OSX. Complex division is broken because file divdc3 is missing. This file comes from libclang_rt.osx.a, a standard LLVM library. This library is missing on OSX.
program test
integer, parameter :: n=2
complex(kind=8), dimension(n,n) :: V
complex(kind=8) :: PER
V(1,1)=cmplx(4.0,2.0)
V(2,2)=cmplx(5.0,3.0)
V(1,2)=0.0
V(2,1)=0.5
PER=cmplx(1.2,1.2)
V(:,:)=V(:,:)/PER
end program test

Undefined symbols for architecture arm64:
“___divdc3”, referenced from:

ld: symbol(s) not found for architecture arm64
flang-new: error: linker command failed with exit code 1 (use -v to see invocation)
