            Bug ID: 95031
           Summary: GCC 10 Analyzer and fatal error: Terminated signal
                    terminated program cc1plus
           Product: gcc

Preprocessed source file dll.ii

Hi Everyone,

I'm trying out the analyzer on a C++ project. I'm working on Fedora 32 with=
 GCC
10.

  $ gcc --version
  gcc (GCC) 10.0.1 20200430 (Red Hat 10.0.1-0.14)

Here's what I am seeing:

  g++ -fPIC -pthread -pipe -DNDEBUG -g2 -O3 -fanalyzer -c dll.cpp
  g++: fatal error: Terminated signal terminated program cc1plus
  compilation terminated.
  make: *** [GNUmakefile:1693: dll.o] Error 1

It is fairly easy to duplicate with live code. Unfortunately, I am not sure
what is needed for a reproducer based on the error message. It can be
duplicated with live code using:

  $ git clone https://github.com/weidai11/cryptopp.git
  $ cd cryptopp
  $ CXXFLAGS=3D"-DNDEBUG -g2 -O3 -fanalyzer" make dll.o
  ...
  g++: fatal error: Terminated signal terminated program cc1plus
  compilation terminated.

Attached is the output with a -save-temps. If someone would kindly provide
instructions, then I would be happy to troubleshot it further.

The file dll.cpp is a real bastard. It includes a lot of template classes. =
Its
sole purpose is to instantiate a bunch of template classes so the object fi=
le
has concrete objects in it. I would not be surprised if some sort of resour=
ce
exhaustion was occurring.=
