For those interested, all the faults found seem to concern dot commands.  Here 
is an example command which was found to cause problems:

.m i 
000\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\0000\\00000000000000\\0\\\\\\\\\\\\\\\\\\\\\\\\\\\\0\\\\\\\\\\000000"0

The next two lines constitute another example:

.h0
.m i 0""""""""""0

I think it’s worth repeating that, as Ryan himself wrote, these faults were 
found in the SQLite command shell tool, not in SQLite itself.  SQLite does not 
recognise the dot commands found here so it would not crash trying to process 
them.  Although there’s an opportunity to examine the command-line shell here, 
those using the SQLite API should not be alarmed purely on the basis of this 
report.

Simon.
