The Boost code looks fine and legal to me: the 
std::allocator<char>::allocate() should return a char* which would assign to 
the variable just fine.  Most of the tests for the iostreams lib are passing 
with Sun-5.9 as well, so I'm guessing either:

* This is a compiler bug: the "Where: Instantiated from non-template code" 
message looks suspicious to me - almost like this is a check on code that 
isn't instantiated at all that's failing.
* Or it's a std lib issue with std::allocator - are you using Sunpro with 
the optional STLport support?  Sun's own std lib is rather old and non-std 
compatible unfortunately.
* Or else the stream is being instantiated with an incompatible allocator 
type - a user error in other words.

Sorry I can't be more helpful, but this should work with that compiler!
