arith.c (arith_power): Call gfc_free_expr in case of error.

Browse Source 
2012-09-15  Tobias Burnus  <burnus@net-b.de>

        * arith.c (arith_power): Call gfc_free_expr in case of error.
        * array.c (gfc_match_array_constructor): Initialize variable.
        (gfc_resolve_character_array_constructor): Remove superfluous check.
        (gfc_array_dimen_size): Add assert.
        * check.c (numeric_check): Fix implicit typing.
        * class.c (gfc_build_class_symbol): Add assert.
        (finalize_component): Free memory.
        * dump-parse-tree.c (show_namespace): Add assert.
        * trans-io.c (transfer_namelist_element, transfer_expr): Avoid
        memory leakage.
        (gfc_trans_transfer): Add assert.
        * trans.c (gfc_trans_runtime_check): Call va_end
