Sorry for the reply-to-self, but I thought I'd take ecpg out of the equation: #include <sys/types.h> #include <pwd.h> int main() { struct passwd p; struct passwd * r; char buf[500]; getpwuid_r(1000, &p, &buf[0], 500, &r); } ... produces the same leak report. Since you didn't include information like the actual errors from valgrind, I can't be sure that the report you are getting is the same as the one I am getting. It could be that in your older version there _is_ something wrong. Perhaps you could post the output of running valgrind --leak-check=full ./testprogram just to be sure? -- Craig Ringer -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
