Yes, I know.

I understand that well enough...what I'm trying to trace at the moment is how value_list
uses type_info.

I don't think so. The actual project is quite complex and the unit test I did (and your
new version of load_jpeg.cpp) does exactly what my project does.
Why the difference in behaviour - I don't know.
The are only a few essential differences in the code:
My actual project record is 12 columns.
I derive from the sql_create_12 structure, and my derived class is what's used in the
insert.
I change the table name with the ::table("Blah") feature.
I've tracked down the problem to the value_list call, and it triggers the type_info
exception on the Null<sql_blob> column.
I'll write back when I find out why.
