Flag to warning about shape/alignment-change of explicit shape arrays arguments

[Jonatan Öström]

Well there are other such (optional) warnings. Truncated integer division for example, or unused variables. It would be reassuring to know that none of the arrays are changing shape, or to see that only the ones so intended do it, especially after doing changes that affect multiple arrays and/or routines.


Regards,

Jonatan

Seems odd to issue a warning for standard conforming code.
