We just updated to clang-16 and are encountering an issue compiling
nettle with -fsanitize=address.
Configured with
CC=clang CXX=clang++ CFLAGS="-fsanitize=address"
LDFLAGS="-fsanitize=address" ./configure --disable-documentation
--enable-x86-aesni
We get the following errors. This doesn't
s of clang didn't have this problem, and just generally
mysterious why the sanitizer would cause the issue. But, it does seem
to be ok now (fwiw sanitizer does report a memory leak when eccdata is
running at the end of make).

Any thoughts on this? Since this runs as part of the build process, it
is blocking one of our pipelines.
