My mistake, I assumed assertions would be enabled in debug mode, but now that I look closely at the configure script, I see an explicit enable_assert option. Couldn't a memory bug overwrite the contents of tp? -----Original Message----- From: users-list [mailto:users-list-bounces+david.b.anderson=citi.com@monetdb.org] On Behalf Of Sjoerd Mullender Sent: Tuesday, July 19, 2016 10:58 AM To: users-list@monetdb.org Subject: Re: MERGE TABLE ERROR -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 On 19/07/16 15:29, Anderson, David B wrote:

The coredump @565 is due to tp being NULL. Since it just got past the assertion @563, the problem has to be down in cs_add().
563 assert(tp); 564 cs_add(&t->tables, tp, TR_OLD); 565 tp->p = t;
I've dug down into cs_add(), but it isn't obvious to me where tp is getting set to NULL. Since it looks like you have a fairly straightforward test case, I would submit a bug report.
Since this is C (not C++) and since cs_add is a function (not a macro), cs_add cannot possibly change the value of tp in the calling function. The only alternative here is that assertions are disabled during configure. In other words, find_sql_table() must return a NULL pointer for whatever reason.

Finally I make it to start it on debugger...
Here is the trace... Can someone help us ? Thks in advance!
