I got the continuous integration going again with: http://git.sv.gnu.org/gitweb/?p=hydra-recipes.git;a=commitdiff;h=f2f1c98b
but then noticed a failure on i686 linux at: FAIL: tests/misc/cut-huge-range.sh (exit: 1) ============================================ cut: error while loading shared libraries: libc.so.6: failed to map segment from shared object I'm not sure about the attached, but it might address the issue. If not we can increase the limit further. thanks, Pádraig.
