emerge --info

dev-db/mariadb-10.1.31-r1 (latest stable) does not compile with gcc 7.3.0 on x86.

Tested other (and also not building) versions:
10.0.35
10.2.15

This is a regression from gcc 6.4.0, as that compiles the same mariadb version in the very same compilation environment properly.
Also, amd64 is not affected, only x86.

As of today, gcc-7.3.0-r3 could successfully build the latest stable mariadb package (version 10.2.22-r1) on x86.
