This is Debian 9.6. gcov says: $ gcov --version gcov (Debian 6.3.0-18+deb9u1) 6.3.0 20170516 This matches the gcc version string exactly. ccache is not being used. configure: using compiler=gcc (Debian 6.3.0-18+deb9u1) 6.3.0 20170516 configure: using CFLAGS=-Wall -Wmissing-prototypes -Wpointer-arith -Wdeclaration-after-statement -Werror=vla -Wendif-labels -Wmissing-format-attribute -Wformat-security -fno-strict-aliasing -fwrapv -fexcess-precision=standard -fprofile-arcs -ftest-coverage configure: using CPPFLAGS= -D_GNU_SOURCE -I/usr/include/libxml2 configure: using LDFLAGS= -Wl,--as-needed I wondered if perhaps gcov's data files are ending in the wrong place for some reason, but I don't know how to verify that. I also wondered if test results would maybe not be saved for the postmaster executable when run under the TAP test framework ... not sure about this. -- Álvaro Herrera https://www.2ndQuadrant.com/ PostgreSQL Development, 24x7 Support, Remote DBA, Training & Services
