I am using the RH7 2.96 series compilers (RH7.1 gcc-2.96-81), which 
(other than the broken RH7 original) are better than any other gcc C++ 
compilers I've used.

I think I've tracked my problem down to a dependency in one of my other 
libraries (Qt1.45) on an older version of libstdc++ (6.1-1).  This 
dependency results in *both* the current libstdc++ (6.2-2) and the older 
version being linked in and apparently causing the problem - if I build 
without Qt things seem to work.

I'm going to try and rebuild Qt with the current library and see if that 
really is the problem.

I'll follow up if it is...
