Description
While it is documented that indexes on NULLable columns are not supported, it would still be better to catch this misconfiguration and produce an error message. Currently such table gets created all right, no errors, no warnings; but an attempt to insert into it causes unspecified error on a release build or an assertion failure on a debug build:
Release build:
MariaDB [test]> insert into t2 values (1),(2),(4),(7);
|
ERROR 1015 (HY000): Can't lock file (errno: 122 "Internal (unspecified) error in handler")
|
Debug build:
mysqld: /home/elenst/bzr/10.0/sql/sql_error.cc:422: void Diagnostics_area::set_error_status(THD*, uint, const char*, const char*
|
): Assertion `! is_set() || can_overwrite_status' failed.

Cannot index nullable column a
