That's what I suspected, for the reasons mentioned in [1].

Now, to check that with libsigsegv it works fine:

  make distclean

  ./configure CPPFLAGS=-Wall --with-libsigsegv 
--with-libsigsegv-prefix=/opt/local
  (use the prefix where you actually have installed libsigsegv)

  make

  Comment out the failing/hanging tests (test-nanosleep, test-pthread,
  test-pthread-rwlock) from gltests/Makefile again.

  make check
