I give enough information for contributors to reproduce my issue (meaningful title, github labels, platform and compiler, command-line ...)
Step to reproduce:
1.get latest commit code (GPAC version 1.1.0-DEV-rev1216-gb39aa09c0-master)
2.compile with --enable-sanitizer
3.make 5 dirs which every of them has a large name(length=255), this makes the file's abs-path lengh larger than 1024, we called it large.nhml
4.run MP4Box -add {path to large.nhml} -new new.mp4
