With the 555 calls of macro_create() it does seem that the builtin macros are being activated. The place that happens is probably the call to macros_create_builtin() in get_config_line() - about line 1029 of readconf.c in master HEAD. There's a commented-out printf on the line before; please uncomment that and run that build (normal debug facilities don't work this early in Exim's startup, unfortunately).
We should discover what the trigger is. -- Cheers, Jeremy -- ## List details at https://lists.exim.org/mailman/listinfo/exim-users ## Exim details at http://www.exim.org/ ## Please use the Wiki with this list - http://wiki.exim.org/
