Hello!

glibc fails to build from source on alpha with many testsuite failures [1]
due to a regression introduced in glibc 2.34 [2].

According to the discussion on the libc-alpha mailing list, this issue
affects multiple architectures for static builds. It just happens that
it causes segmentation faults on alpha [3].

A proposed patch by Adhemveral Zanella has been posted on the list [4]
but not been merged yet. I tested the first version of the patch [3] and
can confirm that it works. I will test the posted version [4] now.

Adhemerval said that he plans to backport the patch down to 2.34, so it
will eventually show up in 2.36 as well. Either way, it might be a good
idea to already carry the patch in Debian but I'm not sure.

Thanks,
Adrian
