That's strange, because I just built the unexec build on a 64-bit
system, and it didn't overflow for me.

Does it overflow on your system during bootstrap, i.e. when it loads
all the Lisp packages in source form?  Or does it overflow when it
loads the *.elc byte-compiled files?  Or is this a native-comp build,
and it overflows when loading the *.eln files?  Or did you discover
the overflow via some method that is nor part of the standard build?

Thanks.
