  Apologies for what is going to be quite light on details as bug reports go,
but I've only just noticed it and I haven't got a simple testcase yet.

  As the subject line says, heap_chunk_in_mb=1536 breaks expect.  The
situation that I'm seeing this in is when attempting to run the binutils
testsuite.

  With heap_chunk_in_mb set to 1536, "make -k check" gets as far as the very
first *.exp file in the binutils testsuite (binutils-all/ar.exp), and then
sits there, spinning its wheels and eating CPU.  It doesn't happen if
heap_chunk_in_mb is set to 1024, 1280, 1408, 1520 and the test run completes.
 It does happen at 1535, and 1532.  At 1528 to 1530 it gets a few testcases
further into the run before stalling.  Probably the exact cut-off point is
environment-dependent.

  Sorry not to have much information, but at least there's a simple
workaround: turn it down a bit.  If I find out more I'll report back.

    cheers,
      DaveK
