Bug ID: 67261
Summary: Demangler infinite recursion
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 goes into an infinite recursion trying to demangle this name:
_ZN1C12_GLOBAL__N_11DINS_1EEEEN1F1GIDTadcldtcvT__E1HEEEERKS5_NS_1I1JE
I don't have the source code to generate this, but it doesn't matter too much
since of course an infinite recursion is always wrong. Anyhow, I believe the
correct demangling is
F::G<decltype (&((((C::E)()).H)()))> C::(anonymous namespace)::D<C::E>(C::E
const&, C::I::J)
The demangler appears to be getting confused about which template to use for a
template parameter. It somehow manages to pick the same template in which the
parameter is defined, which then leads to an infinite loop.

Oops. I should have checked it from the very beginning. The patch proposed for
PR61321 fixes this issue too. The result matches the expected demangling.
