Which version of clang were you using? I have one from pkgsrc and it
claims
/usr/pkg/bin/clang -
Apparently as an alternative to preloading a separate ld.elf_so
and others, I can disable ASLR.
Still unsure what to do with the pthread stuff.
I get the impression I should be compiling everything with asan,
but it's unclear to me how to start to build all of netbsd this
way.

The crazy LD_PRELOAD command is because of this:
==15831==Shadow memory range interleaves with an existing memory mapping. ASan
cannot proceed correctly. ABORTING.

Hi,
I wanted to run our tests with asan/ubsan.
I've used the following:
cd /usr/src
./build.sh ... -O /usr/amd64 release
cd /usr/src/lib/libm
env USETOOLS=never CFLAGS="-fsanitize=undefined -fsanitize=address
-U_FORTIFY_SOURCE" LDFLAGS="-lasan -pthread -lubsan" make -j20
cd /usr/tests/lib/libm
