Paolo,
I've checked all available systems and wasn't able to repro this.
Given your exchanges with Jakub I thought that at this point it was
clear that the issue is real.
Every time vDSO was already filtered with
if (!info->dlpi_name || info->dlpi_name[0] == 0)
return 0;
in FindFirstDSOCallback.
Could you provide additional details of your setup? Or perhaps print
dlpi_name of offending library?
How do I print dlpi_name? And which detail do you want? It's a very,
very, standard Linux machine, running a 3.11.10 kernel and a 2.18 glibc,
two days ago everything was fine, 4_9-branch is fine.
Paolo.
