# gunzip /usr/share/man/man1/hexdump.1.gz <dhildenb> *** stack smashing detected ***: <unknown> terminated Turns out: a) the STFLE instruction in semi-broken on the first invocation b) the code expects a different STFLE behavior than documented in the PoP Fix a) and make sure the code works by adjusting b).
