The TotalView expression system always operates on the original (untransformed) type, never on the transformed type. Trying to evaluate an expression that uses the members of a transformed type directly will fail.

For example, this illustrates the difference between evaluating an expression that dereferences a deque reverse iterator (*rit_int) by calling operator()* for the object , and one that displays rit_int using the STL TTF rules.

Here, however, the expression rit_int.$elide_ptr causes an expression evaluation error because the expression system knows nothing about the transformed type, and thus there is no member named $elide_ptr in the original, untransformed type.
