I've been having a problem with byte-compilation.  There's a certain
(pretty big!) .el file I have that works fine if I load the .el, but
if I byte-compile it and load the .elc, I get immediately get a
message like

  EMACS BUG! INVALID DATATYPE (#o 20) save your buffers and exit blah blah

Further, byte-compiling this file takes a *long* time, on the order of
ten minutes; it seems near the end that at least one GC happens
between every two defuns compiled.  Sometimes, it seems to get hung up
and never complete at all.

When I byte-compile this file with gnuemacs, it zips by in about 10
seconds, and the resulting .elc seems to work fine.

The only thing I can imagine is that the heap size for the epoch is
too small, and the heap size for the gnuemacs I was using was set
large enough.  I poked around, but I don't see what controls the size
of the heap.  Is this a reasonable hypothesis; has anyone noticed
similar problems; any ideas?

Thanks...
