This sounds like a serious bug with OpenSolaris.
But perhaps it is a bug in the script. Can you
reproduce the problem by invoking
make
[^C]
truss -f -o truss.log make
[^C]
and then look at truss.log and see which system calls are
going wrong and why? If it's puzzling please feel free
to compress truss.log and send it along.
