 Use any computed identifier like Floor(numerical_property). A crash will
 occur.

 This happens because when ArcSDEFeatureReader::PrepareStream () is storing
 the column names in an array of colums it doesn't take into account the
 fact sde_wide_to_multibyte () doesn't allocate memory and the result is a
 pointer to a volatile string. This string goes out of block scope and the
 array of columns contains garbage.
