            Bug ID: 102618
           Summary: d-demangle: anonymous symbols are not being properly
                    skipped
           Product: gcc
           Version: 12.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: demangler
          Assignee: unassigned at gcc dot gnu.org
          Reporter: contact at lsferreira dot net
  Target Milestone: ---

According to the D ABI specification, symbol names can contain an arbitrary
number of anonymous symbols. Currently, libiberty can't demangle the following
properly:

_D8demangle9anonymous03fooZ
demangle.anonymous.foo

On the other hand, the official demangler can successfully demangle it as a D
symbol.
