Comment 1 Jakub Jelinek 2002-05-24 17:20:08 UTC

Yes, that's expected. Use -static or allocate it dynamically.
Or you can of course recompile your kernel with TASK_UNMAPPED_BASE changed
in include/asm-i386/processor.h.
The default is 0x40000000 and that's where kernel starts allocating
mmap areas unles they are fixed (and mapping dynamic linker by the kernel
is not fixed).
Alternatively, you could prelink -r the dynamic linker to say 0x80000000
(prelink was included in preview/ dir in 7.2).
