Summary: SQL: segv for unknown identifier in subquery
Initial Comment:
select (select 1) * (select vettecrash from tables);
Program received signal SIGSEGV, Segmentation fault.
[Switching to Thread 0x7f0928f1b6f0 (LWP 22280)]
0x00007f09169c5971 in list_select (l=0x0, key=0x1b92938,
cmp=0x7f091698a3f4 <exp_is_correlation>, dup=0x7f0916988710 <exp_dup>)
at ../../../src/common/sql_list.mx:282
282 list *res = list_create(l->destroy);
I would expect the same error as in:
select vettecrash from tables;
!SELECT: identifier 'vettecrash' unknown
After limiting the problem to a smaller query:
>select (select vettecrash from tables);
Program received signal SIGSEGV, Segmentation fault.
