Crashes during recursive hashing if there is a file on the 7th level or deeper

[vovcacik]

Hi, when I run ssdeep recursively on a directory the program will crash if the target dir contains any file on 7th level or deeper.

More observations:

• the length of absolute path does not matter, i.e. it will crash when run from C:\
• directory or file name length does not matter
• there has to be a file on 7th or deeper level, otherwise it won't crash of there is only empty dir

OS: Windows 10 Pro Reproducibility: 100 % ssdeep -V: 2.14.1

# won't crash
mkdir a\b\c\d\e\f
type nul > a\b\c\d\e\f\6th-level.txt
ssdeep -r a

# will crash
mkdir a\b\c\d\e\f\g
type nul > a\b\c\d\e\f\g\7th-level.txt
ssdeep -r a

# won't crash
hashdeep -r a
md5deep -r a
sha1deep -r a
sha256deep -r a
tigerdeep -r a
whirlpooldeep -r a

Thanks for your report. I'll be investigating.
