--- Comment #29 from Luke Kenneth Casson Leighton <lkcl at lkcl dot net> ---
i tried the same massive 6GB link as was carried out under an i386 (32-bit)
chroot.  this time both of them succeeded.  ld-bfd with --no-keep-memory
succeeded as before with a warning, using only 280mb during the linker
phase (the number of functions called had been increase:
python evil_linker_torture.py 800 400 20 8000000)

ld-gold *also* succeeded, once again requiring 6.5 GB of resident RAM
to carry out the link [on a 64-bit system].

it would appear that the options recommended to use in comment #25 do
not prevent ld-gold from mallocing the full memory of the full size
of the target executable.

consequently, attempting to link a 6 GB executable on a 32-bit system
(with an obvious limit of 4GB) is guaranteed to fail.
