I put a call to byte-run-strip-symbol-positions into readevalloop_eager_expand_eval to get the thing to build. This is probably the cause of the slowdown. It is also surely what is stripping positions from non-function lambdas. This call needs to be taken out, and other things which need it (e.g. Fdefalias) fixed. > > Stefan -- Alan Mackenzie (Nuremberg, Germany).
