            Bug ID: 84925
           Summary: ICE with segfault in __PRETTY_FUNCTION__ (regression
                    over gcc-7)
           Product: gcc
           Version: 8.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: h2+bugs at fsfe dot org
  Target Milestone: ---

Created attachment 43692
  --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=43692&action=edit
code that crashes gcc-8

I have attached a test.cpp

g++-7 (Debian 7.3.0-8) builds this fine.
g++-8 (Debian 8-20180308-1) segfaults on this with

test.cpp:537:25: internal compiler error: Speicherzugriffsfehler
         auto name_ptr = __PRETTY_FUNCTION__;

I have also attached an intermediate file.

Thanks for your help!
