Replying to [comment:20 nickm]:
> 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.
Thanks! Patches look good.
I have
{{{
gcc (Ubuntu 5.4.0-6ubuntu1~16.04.11) 5.4.0 20160609
clang version 3.8.0-2ubuntu4 (tags/RELEASE_380/final)
}}}
and gcc works with the first version of the patch while clang does not.
