Hi Guys,

  I have uploaded a patch for a possible workaround for this problem.  It adds
a new param (max-partial-antic-length) which with its default value will stop
the tree-pre optimization from eating up all the memory on the host system.  It
also adds a testcase for the PR and documents the new param.  Tested without
regressions on an x86_64-linux-gnu toolchain.

  What do you think, should this patch be applied ?

Cheers
  Nick
