Category: Core Group: MonetDB4 "stable" Status: Open Resolution: None Priority: 5 Private: No Submitted By: Ying Zhang (yingying) Assigned to: Nobody/Anonymous (nobody) Summary: Mserver assertion failed at monet_tbl.mx:1747: TBL_M_decref Initial Comment: (stable branch, source code 'cvs up'-ed this morning. compiled with configure option --enable-debug, --enable-assert, --enable-strict, --disable-optimise, on CWI desktop) First load 'module(mapi);' and then load 'module(pathfinder);' seems to cause assertion failure in Mserver: ----------------------- Assertion failure 1: ----------------------- In terminal 1: $ Mserver --dbinit="module(mapi); mapi_register(mil_frontend()); module(pathfinder); " # MonetDB Server v4.32.2 # based on GDK v1.32.1 # Copyright (c) 1993-July 2008, CWI.

Aborted This was caused by the command in terminal 2: $ echo '"blah".print();' | mclient -lmil [ "blah" ] Correct output has been given before the assertion. The assertion was not triggered by any particular MIL statement, as it happens by (seemly) any MIL statement. The assertion won't happen if Mserver was started without 'module(pathfinder);': Mserver --dbinit="module(mapi); mapi_register(mil_frontend()); " or, if 'module(pathfinder);' is loaded before 'module(mapi);': Mserver --dbinit="module(pathfinder); module(mapi); mapi_register(mil_frontend()); " ---------------------------------------------------------------------- >Comment By: Stefan Manegold (stmane) Date: 2009-09-25 15:39 Message: While the assertion indeed should not happen (I can reproduce it with a simple `Ctrl-D` on the mclient console when module mapi is loaded before module pathfinder), the work around is (obviously) to not explicitly load module mapi before module pathfinder, since loading module pathfinder already triggers the load of module mapi, i.e., the following works fine for me: Mserver --dbinit='module(pathfinder); mil_start();' ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=482468&aid=2866544&group_id=56967 ------------------------------------------------------------------------------ Come build with us!
