Hmm, maybe Python is not relevant here, because we have, in gdb/python/py-gdb-readline.c: /* Initialize Python readline support. */ void gdbpy_initialize_gdb_readline (void) { /* Python's readline module conflicts with GDB's use of readline since readline is not reentrant. Ideally, a reentrant wrapper to GDB's readline should be implemented to replace Python's readline and prevent conflicts. For now, this file implements a sys.meta_path finder that simply fails to import the readline module. */ That still leaves open the question about non-GNU/Linux OSs, though. Thanks, Pedro Alves
