This is happening with the QuasiLocalMeasures test suite when run with the Mercurial version of Carpet on Damiana.  It doesn't happen with the Git version (same machine, compiler, optionlist, submit script, etc).  The only change to make this fail is to switch from the Git to the Mercurial version of Carpet.

Luca's error message came just after a message from IsolatedHorizon (the thorn from which QuasiLocalMeasures was derived), so it's probably that which is triggering the error.
