I didn't mention that this was on a pmax.  Since then, I've installed
a virgin copy of gawk from the GNU gawk-2.15.6 distribution, and that
fails too.  However, gawk-3.0.3 works fine.  A gawk-2.15.6 binary
compiled under Ultrix (with gcc 2.7.2.2) works fine...

I'm now starting to suspect a compiler bug (for lack of anything else to
suspect).  I've tried compiling with no optimisation, -O and -O2 with
the same results.  I've not yet delved into the internals of gawk.  Any
suggestions?
