            Bug ID: 27020
           Summary: Stepping over a breakpoint over an exec syscall
                    crashes GDBserver
           Product: gdb
           Version: HEAD
            Status: NEW
          Severity: normal
          Priority: P2
         Component: server
          Assignee: unassigned at sourceware dot org
          Reporter: simark at simark dot ca
  Target Milestone: ---

Running the (soon to be merged, proposed here [1])
gdb.threads/step-over-exec.exp results in failures with the
native-extended-gdbserver board.

To reproduce manually, I run gdbserver with:

$ ../gdbserver/gdbserver --once :1235
./testsuite/outputs/gdb.threads/step-over-exec/step-over-exec-execr-thread-leader-diff-text-segs-false

and GDB with:

$ ./gdb -iex "set confirm off" -iex "set pagination off" -nx
--data-directory=data-directory
./testsuite/outputs/gdb.threads/step-over-exec/step-over-exec-execr-thread-leader-diff-text-segs-false
-ex "set sysroot /" -ex "tar ext :1235" -ex "b main" -ex c -ex "b
my_execve_syscall if 0" -ex c

GDBserver then prints:

Leader going in exec.
Exec-ing
./testsuite/outputs/gdb.threads/step-over-exec/step-over-exec-execr-thread-leader-diff-text-segs-false-execd
/home/smarchi/src/binutils-gdb/gdbserver/linux-low.cc:3665: A problem internal
to GDBserver has been detected.
ptid_t linux_process_target::wait_1(ptid_t, target_waitstatus*,
target_wait_flags): Assertion `step_over_bkpt == null_ptid' failed.
