Bug ID: 67263
Summary: demangler mishandles const qualifier on template
parameter with function type
Product: gcc
Version: 5.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: ian at airs dot com
CC: gbenson at redhat dot com
Target Milestone: ---
The demangler has code to convert from DEMANGLE_COMPONENT_CONST to
DEMANGLE_COMPONENT_CONST_THIS when the const refers to a function type (see the
bottom of d_cv_qualifiers). However, this conversion does not occur when the
const qualifier is on a template parameter that happens to expand to a function
type. Here is a symbol that shows the problem:
_ZN1C12_GLOBAL__N_11DIFbPKNS_1EEEEEvPNS_1FERKT_
The demangler turns that into this:
void C::(anonymous namespace)::D<bool (C::E const*)>(C::F*, bool ( const&)(C::E
const*))
It should produce this:
void C::(anonymous namespace)::D<bool (C::E const*)>(C::F*, bool (&)(C::E
const*) const)
