Perhaps the latter wouldn't help the GNUstep dumping problem because
the use of zones on unexmacosx.c is primarily for the problem that the
dumped heap area cannot be used as an ordinary heap in the dumped
executable, IIUC.  The crucial difference would rather be how
ObjC-related data is located in the executable: Mac OS X uses a
dedicated segment, but GNU/Linux uses the .data section that also
contains other read-write data.

Thanks for testing.

I hope so.  But it is quite unstable in my environment regardless of
dumping.
