interIsoFoam runs into an endless loop

Hello,

when testing interIsofoam i found a parameter set for which it runs in an endless loop. I made same flags to find out where this happens and it is in the file plicRDF.c at line 470 in the while loop starting which while (resIter.found()).

I uploaded a case file with an allrun script to reproduce the error. In my case it got stuck at the time 0.609626.
