            Bug ID: 85309
           Summary: demangler failed with signal 11
           Product: gcc
           Version: 8.0
            Status: UNCONFIRMED

         Component: demangler
          Assignee: unassigned at gcc dot gnu.org
          Reporter: lyberta at lyberta dot net
  Target Milestone: ---

Try to run my C++17 application under GDB I get:

/build/gdb-uGdIdO/gdb-7.12/gdb/cp-support.c:1600: demangler-warning: unable to
demangle
'_ZSt7forwardIRZN3ftz6Engine20ClientNetworkHandler13ProcessEventsEvEUlRT_E_EOS3_RNSt16remove_referenceIS3_E4typeE'
(demangler failed with signal 11)
Unable to dump core, use `ulimit -c unlimited' before executing GDB next time.
/build/gdb-uGdIdO/gdb-7.12/gdb/cp-support.c:1615: demangler-warning: unable to
demangle
'_ZSt7forwardIRZN3ftz6Engine20ClientNetworkHandler13ProcessEventsEvEUlRT_E_EOS3_RNSt16remove_referenceIS3_E4typeE'
(demangler failed with signal 11)

It is a lambda inside ftz::Engine::ClientNetworkHandler::ProcessEvents.
