Re: make check error

[Brian Gough <bjg at network-theory dot co dot uk>]

Thanks for the bug report. 

It looks like there is a new problem with overflow/underflow on RH7,
as this is the second report of this failure.  Unfortunately the test
program does not print anything for the cases which are probably
causing it.

 If someone could try out the patch below it should indicate the line
that is causing the problem (if you can step through that function
with the debugger and see what is going on that will be very useful).

Brian
