Hi,
I have done some testing with 3.2 and now 3.4, visual studio2003 and
boundschecker (and XP). I get a few reported errors when I simply do the
.dump command with no db. Happens on other times with a db, this is easier.
Line numbers are from the downloaded 3.4.0 source. I don’t really know how
the vdbe works, so not sure how to start on solving the write overrun one…
Thanks,
damian
