You are I assume using the Sun C++ compiler, not the GNU one. The following 
might not be the cause of your problem, but it just might be.

It recently came to my attention that the Sun C++ compiler ships with two 
libraries that implement the C++ standard library: libCstd and libstlport.

Basically the standard for C++ has changed in an incompatible way, so to 
maintain backward compatibility, by default the Sun C++ compiler builds with a 
libCstd, which does not support all the features of the standard library.

In order to get a library which conforms more closely to the C++ standard, one 
should use the libstlport library. One needs to add the option -library=stlport4 
for this. If you have multiple objects, they all must be compiled with this 
option - you can't mix the two libraries. See:



1) HP do likewise with their compiler on HP-UX.

2) I don't know if it's true, but according to Wikipedia, there is no compiler 
which fully supports the C++ standard. Sun certainly do not claim to, but 
libstlport is closer to the latest standard than libCstd.
