Re: Question WRT gfortran.dg/allocatable_function_1.f90
Erik,
thanks for looking into this.

Wild guess: without -fbounds-check, gfortran calculates only the shape of
the RHS and assumes that the shape of LHS is the same, but is using a more
literal interpretation when -fbounds-check is used.
While this sounds like a perfectly reasonable explanation ...
In the 'no -fbounds-check'-case we will have a problem if bar() has side
effects, SAVEd variables etc. In that case, calling bar() too few times
may give wrong results.
... this sounds like a potentially ugly bug. Do you think you can
look into this further?
Thanks,
- Tobi
