(as long as you're using a single compiler, anyway - distcc is a little tricky to get working with multiple installed versions of the same compiler) > Anyway, METHOD=devel works well with the non-debug version of our software. Sorry I never mentioned that. I always find myself wanting debugging stuff turned all the way on or all the way off, but John swears by METHOD=devel, and I suppose it can be pretty useful. > Actuall, it causes my application to crash at a completely different point, > even before any NumericVectors are used.

This is crashing for me, too, and it definitely shouldn't be. Looks like something going wrong with find_neighbors and subactive elements, which is 99% likely to be my fault - I only have a little time to check it out today, but I'll give it a shot tonight and tomorrow as well if I can't find the bug right away. --- Roy ------------------------------------------------------------------------------ _______________________________________________ Libmesh-devel mailing list Libmesh-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/libmesh-devel
