Hi again,

I have one more core file, I configured --disable-static and
compiled everything with -g including BerkeleyDB.

System: linux Mandrake, kernel 2.2.14, glibc 2.1.1, gcc version 2.95.2
19991024 (release), physical RAM 128MB, 650MB swap
option wordlist_compress: true

I have got:
FATAL ERROR:WordDBPage::Uncompress read wrong num worddiffs
FATAL ERROR at line:335 !!!

and core file, backtrace:
Core was generated by `./htdig -v -i'.
Program terminated with signal 11, Segmentation fault.
