But the above is useless for any serious debugging, of course. I'm trying to install my GC patches in small increments so that binary search in the version space can point to reasonably small changes. Please try to find out which patch to alloc.c leads to the above problem (if any). Also we need backtrace and stuff, of course. Also don't forget that the makefile dependency rules for lisp.h are missing, so you need to `rm src/*.o' because I've changed the representation of floating point numbers. Stefan
