* | parser: prohibit redefinitions of symbols and verify existance on use | Patrick McHardy | 2014-02-04 | 1 | -0/+7 |
This patch fixes some incorrect behaviour of symbolic variables: - prohibit redefining an existing symbol - verify existance of a symbolic variable during parsing instead of evaluation The second point makes sure we don't allow recursive definitions (var = $var), which lead to a crash due to stack exhaustion.
