Hi,

net-db.test fails in some cirtumstances (build changeroot) because glibc's
gettadrinfo() can return EAI_SYSTEM:

http://sourceware.org/ml/libc-alpha/2012-10/msg00611.html

rpm -q glibc
glibc-2.16.90-7.1.x86_64

Following patch fixed test for me:

The message above suggests that EAI_SYSTEM is now (2.17+) returned when
running out of file descriptors.

That should definitely not be the case when running the test suite, or
that would indicate a real problem in Guile.

Do you have a particular setup to reproduce the EAI_SYSTEM return?

Thanks,
Ludo’.

Hello again,

This may be the same problem as
<http://debbugs.gnu.org/cgi/bugreport.cgi?bug=13958#14>.  That is,
/etc/nsswitch.conf may refer to NSS modules that are not accessible in
your build chroot.

Can you check whether this is the case?

TIA,
Ludo’.
