            Bug ID: 28030
           Summary: ../../gdb/gdbtypes.c:5438: internal-error: Unexpected
                    type field location kind: 4
           Product: gdb
           Version: HEAD
            Status: NEW
          Severity: normal
          Priority: P2
         Component: gdb
          Assignee: unassigned at sourceware dot org
          Reporter: ahajkova at redhat dot com
  Target Milestone: ---

Compile this code with g++ -g sb.C (using any recent GCC, although the line 221
used below is for Fedora's default compiler, gcc-c++-11.1.1-3.fc34):

#include <sstream>
#include <stdio.h>

int main()
{
  std::istringstream in(" abc");
  std::ostringstream out;
  in >> out.rdbuf();
  puts(out.str().c_str());
}

Then run:

gdb -q  -ex start -ex n -ex n -ex step -ex finish -ex step -ex n -ex "br 221"
-ex r a.out

It crashes:

Reading symbols from a.out...
