Bash Version: 4.4 Patch Level: 19 Release Status: release Description: After a function using 'local -' is invoked in a script, alias expansion is disabled, even if it was previously enabled. Repeat-By: In a script, use shopt -s expand_aliases, then call a function containing 'local -'; After the function returns, expand_aliases is disabled. Fix: The issue appears to be caused by set_posix_mode() in builtins/set.def reinitializing posix mode even when its state is unchanged (which resets expand_aliases to 0). Not reinitializing this would be a possible workaround, but I suspect it would be better to explicitly save the state of expand_aliases, as part of get_current_options/set_current_options
