            Bug ID: 28279
           Summary: Assertion `this != current_program_space' failed.
           Product: gdb
           Version: HEAD
            Status: NEW
          Severity: normal
          Priority: P2
         Component: gdb
          Assignee: unassigned at sourceware dot org
          Reporter: andrew.burgess at embecosm dot com
  Target Milestone: ---

While debugging an unrelated issue with the test
gdb.threads/forking-threads-plus-breakpoint.exp I ran into this assertion:

  ../../src/gdb/progspace.c:140: internal-error:
program_space::~program_space(): Assertion `this != current_program_space'
failed.

I was running on x86-64 GNU/Linux.  Build the test executable, then run this
GDB script:

  set height 0
  set trace-commands on
  set sysroot
  set non-stop on
  file
/tmp/build/gdb/testsuite/outputs/gdb.threads/forking-threads-plus-breakpoint/forking-threads-plus-breakpoint
  break -qualified main
  target remote | gdbserver -
/tmp/build/gdb/testsuite/outputs/gdb.threads/forking-threads-plus-breakpoint/forking-threads-plus-breakpoint
  continue
  set breakpoint condition-evaluation host
  set detach-on-fork off
  set displaced off
  break 107 if zero == 1
  continue &

After the 'continue &' I see output like this:

  +continue &
