This is easily reproducible by building gnutls 3.3.x (18, 19, 20 tested) on amd64 and running the guile testsuite until it fails: (sid)ametzler@argenau:/tmp/GNUTLS/gnutls-3.3.20$ cd guile/tests (sid)ametzler@argenau:/tmp/GNUTLS/gnutls-3.3.20/guile/tests$ j=0 ; rm openpgp-auth.scm.log openpgp-auth.scm.trs test-suite.log ; while make test-suite.log TEST_LOGS=openpgp-auth.scm.log ; do j=$(($j+1)) ; sleep .01 ; rm openpgp-auth.scm.log openpgp-auth.scm.trs test-suite.log ; done ; echo xxx $j This will usually be the case after run #1 or #2. The issue not Debian specific, I also see this with GIT stable-2.0. Both Ludovic and me have managed to generate backtraces: http://article.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/8372 http://article.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/8379 cu Andreas -- `What a good friend you are to him, Dr. Maturin.
