'empty_string' is defined in Pike in one place (it could be made static). That empty string is not a char * but something completely different (which generally is undefined). Anyway, in the one place in Pike where it's defined it can be made static (and it fixes the problem). Not sure if any action on the PHP4 side would be desirable. Probably not though. I'll make sure that Pike is patched. -- [ Below is a random fortune, which is unrelated to the above message. ] <<<<< EVACUATION ROUTE <<<<<
