|     Gaby I'm assigning this to you.

Thank you.

|     AFAIK, this class of bugs in 
|     gslice_array
|     mask_array
|     indirect_array

I've fixed the problem for indirect_arrays.  It remains to address
gslice_arrays and mask_arrays.

|     represent the only valid code that I cannot compile with g++/libstdc++.
|     
|     Any thoughts on fixing this? I'm not quite sure what the deal is: is this a problem with the standard, or what? Other libraries don't have problems with this kind of code.

That is a problem in the Standard specification.  Please have a look
at a paper of mine "Fixing valarray for real world use" (accessible
from the LWG website) and DR 253.
