Hey all, I suspect there is a memleak in bash.
I use the bash 4.4.23 (fedora Linux) with ASAN. Then I run some testcases and find a memleak. <http://gnu-bash.2382.n7.nabble.com/file/t3069/gs.png> I think we need to free this "gs" in execute_cmd.c *gs* = sh_getopt_save_istate (); if (subshell == 0) { begin_unwind_frame ("function_calling"); push_context (var->name, subshell, temporary_env); /* This has to be before the pop_context(), because the unwinding of local variables may cause the restore of a local declaration of OPTIND to force a getopts state reset. */ add_unwind_protect (maybe_restore_getopt_state, *gs*); add_unwind_protect (pop_context, (char *)NULL); unwind_protect_int (line_number); unwind_protect_int (line_number_for_err_trap); unwind_protect_int (function_line_number); unwind_protect_int (return_catch_flag); unwind_protect_jmp_buf (return_catch); add_unwind_protect (dispose_command, (char *)tc); unwind_protect_pointer (this_shell_function); unwind_protect_int (funcnest); unwind_protect_int (loop_level); } else push_context (var->name, subshell, temporary_env); /* don't unwind-protect for subshells */ Is this a bug? Just analyze the code. -- Sent from: http://gnu-bash.2382.n7.nabble.com/
