It is hard to say what causes this without seeing the array declaration 
(and the declaration(s) of identifiers used for defining the dimensions).

Simplest solution: use a cast for the argument. Better yet, check where 
that incompatibility comes from. Usually munmap takes a void*, evem on 
Solaris. Do you have some extra POSIX-compatibility options on?

IIRC the default standard C++ library of the Sun C++ Compiler does not 
support member templates (for backward compatibility reasons). The 
conversion between different auto_ptr types requires this feature.

If your library needn't be compatible to the default Sun C++ ABI, you 
can use the stlport library that comes with the compiler instead. It 
should support this.

Otherwise if that line contains an auto_ptr assignment
   foo = bar;

you can make that
   foo = bar.release();
or
   foo.reset( bar.release() );
which should work.

This is all I can say without taking the extra time to get the code :-o
