All,
I dug further into the sql.bind exception, and I think the problem is occurring at:
b = store_funcs.bind_col(tr, c, access);
in mvc_bind(). The call has access = 0 which is readonly and the column c exists, but it looks like NULL is returned to b.
Could the problem be that I am sitting the the "sys" schema, but I should be placing all of my tables into another one?
Thanks,
Dave

Subject: Merge/Remote table causes segfault
All,
I've been able to isolate the seg-fault in gdb, but am not sure how to proceed. Should I file a bug report? There is a NULL pointer access in q_enqueue_(). The q data pointer is NULL. If I look at the flow inside the flow event d, I see the error: "SQLException:sql.bind:unable to find sys.loan201508(purpose)", so it looks like the root cause is higher up/elsewhere.
