--- Comment #7 from Martin Sebor <msebor at gcc dot gnu.org> ---
The optimization is meant to be independent of the warning.  If it isn't it's a
bug in the code.

I successfully tested the pass on powerpc64le just last week, but I did not
test it on any ILP32 targets.  Let me look into this.

In the meantime, the optimization can be disabled by initializing the
-fprintf-return-value option to 0, without disabling anything else.
