Re: Segfault on long memo fields

Hi Nigel,

If it isn't sensitive data, can you upload a copy of the database  
somewhere? I can run it under the debugger, and see what's causing  
the segfault. It does sound like a buffer overflow problem to me too.

Alternatively, try building a debug version of mdb-tools and running  
it under gdb. That will show you where it is crashing.

Regards, Brett
