Monetdb is segfaulting, probably while interpreting a query or planning it. I first thought it had to do with data, but after emptying the tables, the query still makes monetdb segfault. Please, please, state your platform/version ... as it ran fine on the development branch
Error in syslog says:
[ 1230.812708] mserver5[5369]: segfault at 7fab4c2b5ff8 ip 00007fab4f894285 sp 00007fab4c2b6000 error 6 in lib_sql.so.2.30.2[7fab4f7e3000+116000]
Following is the faulty ddl / query. Is there anything I can do to help debug this ? For the dev guys that want to debug this; I'm giving it a shot aswel:
(gdb) bt #0 0x00007fa1097718ec in prop_destroy (p=0x0) at ../../../src/server/rel_prop.mx:54 #1 0x00007fa10977190a in prop_destroy (p=0x39165f8) at ../../../src/server/rel_prop.mx:56 #2 0x00007fa10977190a in prop_destroy (p=0x3916658) at ../../../src/server/rel_prop.mx:56 #3 0x00007fa10977190a in prop_destroy (p=0x3916688) at ../../../src/server/rel_prop.mx:56 #4 0x00007fa10977190a in prop_destroy (p=0x3916748) at ../../../src/server/rel_prop.mx:56 #5 0x00007fa10977190a in prop_destroy (p=0x3916778) at ../../../src/server/rel_prop.mx:56 #6 0x00007fa10977190a in prop_destroy (p=0x39167d8) at ../../../src/server/rel_prop.mx:56 #7 0x00007fa10977190a in prop_destroy (p=0x3916808) at ../../../src/server/rel_prop.mx:56 #8 0x00007fa10977190a in prop_destroy (p=0x3916898) at ../../../src/server/rel_prop.mx:56 #9 0x00007fa10977190a in prop_destroy (p=0x39168c8) at ../../../src/server/rel_prop.mx:56 #10 0x00007fa10977190a in prop_destroy (p=0x3916928) at ../../../src/server/rel_prop.mx:56 #11 0x00007fa10977190a in prop_destroy (p=0x3916958)
...goes on and on.
(gdb) list 49 #include "rel_semantic.h" 50 #include "rel_prop.h" 51 52 void 53 prop_destroy( prop *p ) 54 { 55 if (p->p) 56 prop_destroy(p->p); 57 _DELETE(p); 58 }
just a guess:
might be a stack overflow due to too deep recursion.
