Comment:
For me, the previous changes work with GCC and -O0, but fail with clang
and -O0. The configuration that reproduces the failure with the original
version of the patch but which succeeds with the second is:
{{{
./configure --disable-module-dirauth --disable-gcc-hardening CC=clang
CFLAGS='-O0'
}}}
(The `--disable-gcc-hardening` part is necessary to turn off
FORTIFY_SOURCE, which is not compatible with `-O0`.)
For me, both versions of the patch work with GCC. My GCC is 9.2.1; my
clang is 8.0.0.
