This sometimes happen especially if you have complex expressions which generates
complex types. Often times, the problem is only seen at debug mode where the
functions are not fully inlined by the compiler. The solution is to break down
your expressions (sepecially subrules) into smaller chunks.

The basic_chset template is in "utility", and everything in "utility" depends on various bits and pieces of "core".  basic_chset is derived from unary, which is defined in core/composite.   A Gordian knot... and me without a sword.

This has been fixed in the current CVS but unfortunately didn't make it into
the Spirit 1.6 branch yet. Hopefully, a maintenance upgrade (v1.6.1) will be
provided. You can simply change all occurrances of "arg" to "arg_" to fix
the problem. Alternatively, you can update from the Spirit CVS, branch
BRANCH_1_6.

This is again a VC++ bug.
