Ksh was not checking for `command` when running a special builtin, which caused preceding invocation-local variable assignments to become global. This is the reproducer from the att/ast#72: $ foo=BUG command eval ':' $ echo "$foo" This no longer prints 'BUG', as ksh now makes sure the command builtin is not running a special builtin before making invocation-local variable assignments global. src/cmd/ksh93/sh/xec.c: - Backport the bugfix for BUG_CMDSPASGN from ksh93v- 2013-10-10-alpha. src/cmd/ksh93/tests/builtins.sh: - Add a regression test based on the reproducer in att/ast#72. |
