Please ignore the previous patch, the root cause is the following section
tapsets.cxx: dwarf_derived_probe::saveargs
/* trick from visit_target_symbol_context */
target_symbol *tsym = new target_symbol;
token *t = new token;
tsym->tok = t;
tsym->base_name = "$";
tsym->base_name += arg_name;
The empty token is created, I will fix it soon.
Also any suggestion is welcome!
Regards,
Wenji
