--- Comment #14 from clyon at gcc dot gnu.org ---
I confirm what I observed is a testsuite harness problem, for which I proposed
a patch here:
https://gcc.gnu.org/ml/gcc-patches/2014-10/msg01792.html
dejagnu-1.5 (as shipped with Ubuntu 14.04) masks the problem I was facing with
dejagnu-1.4.4-X as shipped with RHEL5).
