Hm. Not entirely clear on what's going on yet. I've run the tests on hydra (community ppc 64 machine), which is pretty similar to termite which failed [1] with: TRAP: BadArgument("!(((context) != ((void *)0) && (((((const Node*)((context)))->type) == T_AllocSetContext) || ((((const Node*)((context)))->type) == T_SlabContext))))", File: "/home/pgbuildfarm/buildroot-termite/HEAD/pgsql.build/../pgsql/src/backend/utils/mmgr/mcxt.c", Line: 1010) The best theory I have so far that I have is that slab.c's idea of StandardChunkHeader's size doesn't match what mcxt.c think it is (because slab.c simply embeds StandardChunkHeader, but mcxt uses MAXALIGN(sizeof(StandardChunkHeader))). That's not good, but I don't quite see how that'd cause the issue, since StandardChunkHeader's size should always be properly sized. Tomas, do you have access to termite (which appears to be run by Craig, under company mail). If not, I can push a "blind" fix, but I'd rather have more information.
