--- Comment #1 from kargl at gcc dot gnu.org ---
This is not a gfortran bug. Adding code to use exp() and log(),
I compiled the modified code:
s0 = s0 + i**(0.05 + n)
s1 = s1 + exp(0.05 + n)
s2 = s2 + log(0.05 + n)
with the -fdump-tree-optimized option. Looking at the dumped info,
one finds the three lines
_107 = __builtin_powf (_103, _106);
_109 = __builtin_expf (_105);
_111 = __builtin_logf (_105);
If I compile the code with "-S -O3" and look at the assembly code
I see
call powf
call expf
call logf
which are math functions contained in your system's libm. So, this
is an issue with your libm not gfortran. I'll let someone else judge
whether the bug should be closed with INVALID or WONTFIX.
