While looking at pr86312, I realized that this not the case: when the warning
is emitted at run time, the file generated by -fdump-tree-original contains
lines such as:
_gfortran_runtime_warning_at (&"At line 12 of file pr86312.f90"[1]{lb: 1
sz: 1}, &"An array temporary was created"[1]{lb: 1 sz: 1});
So the question is why such lines are sometime emitted and sometime not.
