Hi Cyrill,
Yes, I am using the latest version:

commit e2ed7b7e125e03646d3be537b11d1b46b9c3f506 (HEAD -> master, origin/master,
origin/HEAD)


I guess you may use the wrong sanitizer? 

Here is my command to build nasm with memory sanitizer:


#!/bin/bash

BIN_PATH=$(readlink -f "$0")


CC=afl-clang CXX=afl-clang++ CFLAGS="-g -O0 -fsanitize=memory
-fsanitize-memory-track-origins=2 -fno-omit-frame-pointer" CXXFLAGS="-g -O0
-fsanitize=memory -fsanitize-memory-track-origins=2 -fno-omit-frame-pointer "
./configure --prefix=$(dirname ${BIN_PATH})/build
        make
        make install


Please take a look. 
I double-check two bugs I submitted. They are still not fixed in the latest
version
