With LAST_UPDATED Fri Jun 26 21:36:32 CEST 2020 Fri Jun 26 19:36:32 UTC 2020 (revision 0fce12c0920:2873383514d:0801f419440c14f6772b28f763ad7d40f7f7a580) (a.k.a r11-1677) I just tried to build on CompileFarm gcc24, which is a "EdgeRouter Pro" mips64 with 2 GB memory but no swap, and with "gcc version 8.3.0 (Debian 8.3.0-6)". Needless to say, genautomata fails. Also tried in vain: configuring with --enable-checking=release.
