The problem is that constant_value_1 has the following code: if (!init || !TREE_TYPE (init) || (integral_p ? !INTEGRAL_OR_ENUMERATION_TYPE_P (TREE_TYPE (init)) : (!TREE_CONSTANT (init) /* Do not return an aggregate constant (of which string literals are a special case), as we do not want to make inadvertent copies of such entities, and we must be sure that their addresses are the same everywhere. */ => || TREE_CODE (init) == CONSTRUCTOR || TREE_CODE (init) == STRING_CST))) So it does not consider string constant as constant initializers. I think this is probably breaking more than this warning. -- manu at gcc dot gnu dot org changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |manu at gcc dot gnu dot org Status|UNCONFIRMED |NEW Ever Confirmed|0 |1 Last reconfirmed|0000-00-00 00:00:00 |2010-02-21 01:27:20 date| | http://gcc.gnu.org/bugzilla/show_bug.cgi?id=31843 ^ permalink raw reply [flat|nested] 3+ messages in thread
