I've reproduced John's error on 10.6.8 applying webrev.4 on top of jdk8/tl.

Am setting ALT_BOOTDIR to 1.7.0_04 as built from jdk7u-dev on Mar 4.

Here's what -Xinternalversion reports from that build:

  OpenJDK 64-Bit Server VM (23.0-b16) for bsd-amd64
  JRE (1.7.0_04-internal-stephen_2012_03_04_02_12-b00),
  built on Mar  4 2012 02:23:33 by "stephen" with gcc 4.2.1
  (Based on Apple Inc. build 5658) (LLVM build 2335.6)

This is how I setup the repo, applied patches and initiated the build:

  https://gist.github.com/1980690

The error occurs running ./test_gamma:
  ...
  echo "Doing vm.make build:"
  Doing vm.make build:
  All done.
  cd bsd_amd64_compiler2/product && ./test_gamma
