Attempt #4:
Rebuild with asan
make clean
make CXXFLAGS="-g -O1 -fsanitize=address"
make check
I don't know if this is coincidence, or actually meaningful, but the
test "Testing protocol success with smtp (stdin)" finds one memory leak.
220 OK
smtp: Succeeded: 220 OK
=================================================================
==3035435==ERROR: LeakSanitizer: detected memory leaks
Direct leak of 13 byte(s) in 1 object(s) allocated from:
#0 0x7f64762edd10 in strdup ../../../../src/libsanitizer/asan/asan_interceptors.cpp:578

#3 0x563a16835173 in cli_main(int, char**) /home/bremner/software/debian/nullmailer/protocols/protocol.cc:138
SUMMARY: AddressSanitizer: 13 byte(s) leaked in 1 allocation(s).
Looking at the code there is indeed a leak, but it's hard to see how it
would lead to a crash.
