On amd64, valgrind 3.3 complains about uninitialized memory in BoostTest 1.35.0:
==15894== Syscall param sigaltstack(ss) points to uninitialised byte(s)
==15894== at 0x58AB717: sigaltstack (in /lib/libc-2.7.so)

Peter Klotz provided a patch (attached) that fixes this bug by initializing the
structure passed
to syscall sigaltstack().
Gennadiy Rozental has applied it upstream.
