Thanks for following up.

This is also confirmed by checking with e.g. NAG.  Thus closing.

that the code is not conforming, so this issue can be closed.

"In this case, the standard essentially places the onus on the program (and by
extension its author) to conform, the processor (compiler being part of it) is
not required to issue diagnostics.

And the issue is this: with the defined assignment as specified, the standard
semantics requires the 'ialloc` to be allocated to the right shape prior to
assignment on line 23: "ialloc = ["4","9"]".

You can retry with `allocate( ialloc(2) )` statement preceding the above
assignment and check the program response."
