It will not help. I guarantee you.

I have debugged this to the point where I am sure that enblend isn't
needing more memory than is available, but it is going bonkers and
suddenly ends up doing the equivalent of:
while (1)
malloc (ALOT);
The gnu-malloc changes strategies of allocating memory after a while
(when the first strategy starts to fail), enblend continues until
it completely runs out.
On 64 bit systems it allocates WAY more than on a 32 bit system and
after a while (a few milliseconds in fact) the system determines that
allocating several gigabytes is one thing, but then trying to use it
is never going to work, so it starts refusing the alloc requests too,
even though it hasn't run out of adressing space yet.
I personally suspect the tile cache code. Due to the use it is getting
in enblend, somehow getting stuck in a "I need more memory to allocate
more memory" loop or something like that.
Rogier.
