Package: libpqxx3-dev
Version: 3.0.2-1
Severity: normal
The following piece of code gives me a memleak (valgrind report)
#include <pqxx/pqxx>
int main(int argc, char **argv) {
pqxx::connection t("host=127.0.0.1 username=changeme password=changeme
dbname=changeme connect_timeout=10");
pqxx::work work(t, "transaction");
work.abort();
}
Compile with:
g++ -o main main.cpp -lpqxx
