Hi Noel,

I will try to cut down the optimization level to see; thanks.

Hi Hubert,

Looks like the Sandia-vacpp-10.1 tester ran last night using gcc to build
bjam.  It's beginning to look like a problem with xlc at high optimization,
does that sound plausible?

      Hi Noel,

      The bjam built with GCC on AIX and Linux PPC does not core
      immediately.
      I have not confirmed if they will work fine for a full run of the
      tests.

      I will try to isolate the issue if time permits.

      Thanks,

      Yes.

      Yes, it works fine with gcc-4.1.2.  The problem is specific to xlc,
      as
      in:

      ./build.sh vacpp

      produces

      bin.unknownppc/bjam

      which cores.  Perhaps Hubert can confirm that gcc builds a good bjam?

      Steven, I lack the time tonight to debug this but will change over
      our
      tests to use gcc to compile bjam and that should be a short term
      workaround.  I'll attempt to look at this over the weekend and answer

      your questions then.

      Thanks for the help.
