I think it's a legitimate complaint that postmaster.log wasn't captured in this failure, but that's a buildfarm script oversight and hardly Andres' fault. In any case, valgrind failures are generally easy enough to reproduce locally. Meanwhile, over on https://buildfarm.postgresql.org/cgi-bin/show_log.pl?nm=snapper&dt=2017-11-23%2013%3A56%3A17 we have ccache gcc-4.7 -Wall -Wmissing-prototypes -Wpointer-arith -Wdeclaration-after-statement -Wendif-labels -Wmissing-format-attribute -Wformat-security -fno-strict-aliasing -fwrapv -fexcess-precision=standard -g -g -O2 -fstack-protector --param=ssp-buffer-size=4 -Wformat -Werror=format-security -I../../../../src/include -D_FORTIFY_SOURCE=2 -D_GNU_SOURCE -I/usr/include/libxml2 -I/usr/include/mit-krb5 -c -o generation.o generation.c generation.c: In function ‘GenerationContextCreate’: generation.c:206:7: error: static assertion failed: "padding calculation in GenerationChunk is wrong" make[4]: *** [generation.o] Error 1 Looks to me like GenerationChunk imagines that 3*sizeof(pointer) must be a maxaligned quantity, which is wrong on platforms where MAXALIGN is bigger than sizeof(pointer). regards, tom lane
