A fix has been uploaded in libc0.3 2.24-5. We however now need to wait
for p11-kit to be rebuilt with that libc in order to get the fix in (you
don't want to know why).

Thanks for the investigation!

Package: libc0.3
Version: 2.24-4
Severity: normal
Control: affects -1 cupt

Hello Samuel and all,

Thank you for fixing #839742, the original test case now passes.

Unfortunately, it was not enough for Cupt test suite on Hurd, since the
bug still happens under another circumstances - namely, if the
caller itself (executable or shared library) links to pthread.

Updated test case attached.
