--- Comment #19 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
for the original testcase in comment #0, renaming main to f and changing the
return type to void, the trunk of GCC can optimize the function to just a
return now.

Note the renaming is because of inlining heurstics and the call to reserve is
not being inlined.

So we can close this as fixed.
