At least we are convinced it's eglibc 2.10.1, not 100% sure it is due to
NPTL.
I have done some more tests, showing it's a bit more complicated than
that. apt-get from stable/testing/unstable:
- works with libstdc++6 built against eglibc 2.9
- segfaults with libstdc++6 built against eglibc 2.10.1
Then I tried to rebuild apt against the "broken" libstdc++6.
Surprisingly this new apt-get:
- works with libstdc++6 built against eglibc 2.10.1
- segfaults with libstdc++6 built against eglibc 2.9
So in short, it seems that using eglibc 2.10.1 to build libstdc++6
triggers an ABI change on this library. I haven't investigated more for
now, I am not sure when I'll have time to do it.
