Hi Andrew, I noticed your animal lorikeet failed in the last two runs: https://buildfarm.postgresql.org/cgi-bin/show_log.pl?nm=lorikeet&dt=2018-02-21%2009%3A47%3A17 TRAP: FailedAssertion("!(((PageHeader) (page))->pd_special >= (__builtin_offsetof (PageHeaderData, pd_linp)))", File: "/home/andrew/bf64/root/HEAD/pgsql/src/include/storage/bufpage.h", Line: 313)
https://buildfarm.postgresql.org/cgi-bin/show_log.pl?nm=lorikeet&dt=2018-02-20%2012%3A46%3A17 TRAP: FailedAssertion("!(PMSignalState->PMChildFlags[slot] == 1)", File: "/home/andrew/bf64/root/HEAD/pgsql.build/../pgsql/src/backend/storage/ipc/pmsignal.c", Line: 229) 2018-02-20 08:07:14.054 EST [5a8c1c3b.21d0:3] LOG: select() failed in postmaster: Bad address 2018-02-20 08:07:14.073 EST [5a8c1c3b.21d0:4] LOG: database system is shut down The difference between the last successfull and the last failing build is a single comment typo commit. It kinda looks like there might be some underlying issue on the machine with shared memory going away or such? Greetings, Andres Freund
