Same here and I don’t think we got a report upstream in GnuTLS either.

Would it be an option for you to have a ‘guile3-gnutls’ package so
‘guix’ can depend on it?

If you can reproduce the hang, could you attach gdb to the two processes
that run tests/reauth.scm (it forks)?

On the ‘gnutls_3_6_X’ branch, I can run the following loop for a while
without experiencing the issue (on x86_64-linux-gnu):

  while make check TESTS=tests/reauth.scm ; do : ; done

Thanks in advance,
Ludo’.
