Problem description: | |
Problem was reported in a special build of 12.10.FC9W1 on sol64 and the test case that I created confirms the problem reproduces on linux x86_64 running 12.10.FC9W1 and 12.10.FC12W1. Upon failure the a sample stack from a 121.10.FC12W1 server on linux x86_64 will look like: 0x0000000001422ae9 (oninit) afstack 0x00000000014265d1 (oninit) mt_ex_throw_sig 0x000000000142f743 (oninit) afsig_handler 0x0000003ddfa0e4c0 (Linux) 0x00000000015dc77c (oninit) lddblnull 0x00000000013ba340 (oninit) rdatavalFloat 0x0000000000a5faa7 (oninit) valload 0x000000000089b3d0 (oninit) geval 0x0000000000825e17 (oninit) evalcols 0x00000000008270b0 (oninit) getrow 0x00000000008276b8 (oninit) fetchrow 0x0000000000827cbf (oninit) doselect 0x00000000008a500f (oninit) exsubq 0x000000000165b22f (oninit) ev_cb 0x000000000165a6fe (oninit) new_eval 0x000000000081c7ea (oninit) gettupl 0x0000000000820074 (oninit) scan_next 0x0000000000b8091d (oninit) join_next 0x0000000000b80f65 (oninit) join_next 0x0000000000b80f65 (oninit) join_next 0x0000000000b80f65 (oninit) join_next 0x0000000000b81f29 (oninit) next_row 0x0000000000b828d1 (oninit) get_first_row_from_producer 0x0000000000b84fc6 (oninit) hash_process_all_groups 0x0000000000b869a6 (oninit) group_open 0x0000000000b8659b (oninit) group_open 0x000000000080f4c9 (oninit) filltemp 0x00000000008174bf (oninit) scan_open 0x0000000000805038 (oninit) materialize_viewtmp 0x0000000000823c86 (oninit) prepselect 0x0000000000a4288e (oninit) open_cursor 0x0000000000a4a709 (oninit) sql_open 0x0000000000a4a8f6 (oninit) sq_open 0x0000000000b0d291 (oninit) sqmain 0x000000000154fecb (oninit) spawn_thread 0x0000000001414520 (oninit) th_init_initgls 0x0000000001459f77 (oninit) startup | |
