Re: [RFC] type safe trees

If you're using the current HEAD, you should know that there's a bad performance bug in which the GC settings are wrong when --disable-checking is in effect. If you're seeing GC happen when building combine.c in a bootstrap, you either forgot --disable-checking, you're seeing this bug, or you need to go buy more RAM (even my laptop, with 256Mb of RAM, doesn't GC while building combine.c with the computed --param ggc-min-heapsize=65536).

Would you please describe this bug in more detail? Do you know how to fix it?
