Hi. As mentioned here: https://bugzilla.opensuse.org/show_bug.cgi?id=1123136
there's a new issue with GCC 9, it's related to: https://gcc.gnu.org/gcc-9/porting_to.html#complit in: /* Not const! Never return this as a result directly! */ #define SMTP_ADDRESS_LITERAL(localpart, domain) \ &((struct smtp_address){ (localpart), (domain) }) Thanks, Martin
