Hi Roy, No, you are entirely right: in dbg mode, the runtime error appears in any example. I have just arbitrarily chosen ex4 to show you the error; sorry for any confusion here. I have just tried devel mode, and, same as in opt mode, everything seems to be perfectly fine here ... -Anna ------------------------------------------------------------------------------ Start uncovering the many advantages of virtual appliances and start using them to simplify application deployment and accelerate your shift to cloud computing http://p.sf.net/sfu/novell-sfdev2dev _______________________________________________ Libmesh-users mailing list Libmesh-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/libmesh-users
