Roberto,
    Have you done any build of ppl 0.11.2 against the llvm-gcc or clang
compilers? Mac OS X 10.7 (Lion) defaults to llvm-gcc and the fink project
has switch to clang for their 10.7 builds. Both llvm based compilers produce
a ppl 0.11.2 build which fails a subset of tests. For example the second build
of affineimage1 in Box fails with...

[MacPro:build/tests/Box] root# ./affineimage1
tests failed: test08

The problem occurs with both llvm-gcc-4.2 and clang3.0svn from Xcode 4.1 as
well as current clang svn. We should try to find out if this is a bug in
ppl or in the llvm backend of the llvm-gcc and clang compilers. Thanks in
advance for any help in pinning this down.
          Jack
ps The problem isn't system related since the Xcode gcc-4.2 compiler still
produces a ppl build with no testsuite regressions. Apple will be depeciating
the gcc-4.2 compiler out of Xcode in favor of llvm-gcc-4.2 at some point so
we do need to address these ppl failures under llvm-based compilers.
