Waldemar Brodkorb:
I found a few interesting things. The test binaries are compiled by
openadk with the "initial" GCC and not the "final" one. The
difference is that the implementation of the unwinder code is then
taken from libgcc.a. I get the same behavior if I explicitly add this
library to the list of objects to link into the test binary. With a
final version of GCC, the implementation is taken from libgcc_s.so as
it should and the behavior is maybe not ideal but to me it looks far
better (is that because the initial GCC doesn't really implement any
unwinder code?).
BTW, the initial GCC is built with --disable-threads. Could that
possibly be the reason some of the tests in nptl fail?

As I
said, I used d4d4f37 and not strictly origin/master. But I
otherwise used the command line you gave me, including --libc-source.
But 17ad14e5780533db90171e16b95dbeda4e81ffb0 contains a workaround
for exactly the seen problem.
