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
