--- Comment #3 from Martin Sebor <msebor at gcc dot gnu.org> ---
With GCC 7.0.0 20160927 configured with --build=x86_64-pc-linux-gnu
--host=x86_64-pc-linux-gnu --target=arm-none-eabi I get the expected output
(below).  I see failures in other tests in the results reported for
arm-unknown-linux-gnueabihf below but none in the builtin-sprintf-warn-4.c
test:
https://gcc.gnu.org/ml/gcc-testresults/2016-09/msg02201.html

Can you please check again?
