Error encountered when calling ioctl

[alxchk]

I have strange issue with mcfly in root/bash (zsh/user works fine). The crash happens when item selected and tab pressed (i.e. when completion should be passed to the terminal). I can't see this at screen (because terminal cleared) however can from strace:

fcntl(3, F_SETLK, {l_type=F_RDLCK, l_whence=SEEK_SET, l_start=1073741826, l_len=510}) = 0
