I use gdb 7.8 compiled on Linux (RedHat) with python 2.7.2 support. When I type the following commands: (gdb) python >help() >end The first part of python help is displayed and a 'help>' prompt is displayed. But I can no more enter commands to display the end of the help. I need to suspend/restore gdb using CTRL-Z and fg to be able to enter new commands.

E.g,. $ echo 'main(){*(int*)0=0;}' | gcc -x c -; ./gdb/gdb -batch -ex r ./a.out Program received signal SIGSEGV, Segmentation fault. 0x00000000004004ff in main () $ If you start typing the next command, seemingly nothing happens - GDB left the terminal with echo disabled. The issue is that that "r" ends up in fetch_inferior_event, which calls reinstall_readline_callback_handler_cleanup, which causes readline to prep the terminal (raw, echo disabled). But "-batch" causes GDB to exit before the top level event loop is first started, and then nothing de-preps the terminal. The reinstall_readline_callback_handler_cleanup function's intro comment mentions: "Need to do this as we go back to the event loop, ready to process further input." but the implementation forgets the case of when the interpreter is sync, which indicates we won't return to the event loop yet, or as in the case of -batch, we have not started it yet. The fix is to not install the readline callback in that case. For the test, in this case, checking that command echo still works is sufficient. Comparing stty output before/after running GDB is even better. Because stty may not be available, the test tries both ways. In any case, since expect's spawn (what we use to start gdb) creates a new pseudo tty, another expect spawn or tcl exec after GDB exits would not see the wrong terminal settings. So instead, the test spawns a shell and runs stty and GDB in it.
