--- Comment #44 from Mark Wielaard <m...@klomp.org> ---
Both helgrind/tests/tls_threads and helgrind/tests/tls_threads2 fail because if
this warning:

+WARNING: could not find symbol for var stack_cache_actsize in libpthread.so.0
+=> pthread stack cache cannot be disabled!

I thought this was fixed by:

commit 2de91d914cc5ed4ed7ea8e70d5e06c46e991f39f

    Bug 444488 - Use glibc.pthread.stack_cache_size tunable

    Try to use GLIBC_TUNABLES to disable the pthread stack
    cache.

This machine has glibc 2.39 so should have tunable support.
$ /usr/lib/ld-linux-riscv64-lp64d.so.1 --list-tunables | grep stack_cache_size
glibc.pthread.stack_cache_size: 0x2800000 (min: 0x0, max: 0xffffffffffffffff)

So it isn't immediately clear why it tries to find the stack_cache_actsize var
in libpthread.so.0
