I can't imagine why a different kernel version would cause differences
in results like this, unless the new kernel is somehow leading to
database file corruption, which is pretty scary - although you'd notice
this elsewhere. I think a more likely explanation would be bugs in the
compiler or C/C++ libraries in Mandrake 8.0. Have a look for any update
packages they release.
I'm not all that familiar with Mandrake, but I know that most point-zero
releases of Red Hat (6.0, 7.0) had all sorts of problems that were found
and fixed after release, including C library bugs.
If you simply copied the htsearch binary from your Mandrake 7.1 or RH 6.2
system to Mandrake 8.0, you may try compiling ht://Dig on 8.0 instead.
If you did compile on 8.0, you may want to try the Mandrake 7.1 or RH 6.2
htsearch binary instead. This might help pinpoint whether the problem is
the compiler or libraries.
