perhaps cursor is invalid...?
no,
line 945... of graphcore.cc
void oqgraph::row_ref(void *ref_ptr) throw()
{
reference &ref= *(reference*) ref_ptr; <-- ref ends up having junk
(0xa5a5a5a5) in it
if (cursor)
cursor->current(ref);
else
ref= reference();
}
So, looking at what I can find on mysql: position() gets called after each
rnd_next()
So maybe our bug is in there...
So using the debugger, it appears rnd_next() is NOT called in this case?
