The number of trigger arguments is stored as an int16, but there was no

in an invalid negative value being stored.

Check that the number of arguments does not exceed INT16_MAX.

* [PATCH v1] Reject too many arguments in CREATE TRIGGER

The number of trigger arguments is stored as an int16, but there was no

in an invalid negative value being stored.

Check that the number of arguments does not exceed INT16_MAX.

* [PATCH v1] Reject too many arguments in CREATE TRIGGER

The number of trigger arguments is stored as an int16, but there was no

in an invalid negative value being stored.

Check that the number of arguments does not exceed INT16_MAX.

* [PATCH v1] Reject too many arguments in CREATE TRIGGER

The number of trigger arguments is stored as an int16, but there was no
check that the number of arguments fits in that type.  This could result
in an invalid negative value being stored.

Check that the number of arguments does not exceed INT16_MAX.

Check that the number of arguments does not exceed INT16_MAX.

* [PATCH v1] Reject too many arguments in CREATE TRIGGER

The number of trigger arguments is stored as an int16, but there was no

Check that the number of arguments does not exceed INT16_MAX.

* [PATCH v1] Reject too many arguments in CREATE TRIGGER

The number of trigger arguments is stored as an int16, but there was no

in an invalid negative value being stored.

Check that the number of arguments does not exceed INT16_MAX.

* [PATCH v1] Reject too many arguments in CREATE TRIGGER

The number of trigger arguments is stored as an int16, but there was no

in an invalid negative value being stored.

Check that the number of arguments does not exceed INT16_MAX.

* [PATCH v1] Reject too many arguments in CREATE TRIGGER

The number of trigger arguments is stored as an int16, but there was no
check that the number of arguments fits in that type.  This could result
in an invalid negative value being stored.

Check that the number of arguments does not exceed INT16_MAX.

Check that the number of arguments does not exceed INT16_MAX.

* [PATCH v1] Reject too many arguments in CREATE TRIGGER

The number of trigger arguments is stored as an int16, but there was no

Check that the number of arguments does not exceed INT16_MAX.

* [PATCH v1] Reject too many arguments in CREATE TRIGGER

The number of trigger arguments is stored as an int16, but there was no

in an invalid negative value being stored.

Check that the number of arguments does not exceed INT16_MAX.

* [PATCH v1] Reject too many arguments in CREATE TRIGGER

The number of trigger arguments is stored as an int16, but there was no

in an invalid negative value being stored.

Check that the number of arguments does not exceed INT16_MAX.

* [PATCH v1] Reject too many arguments in CREATE TRIGGER

The number of trigger arguments is stored as an int16, but there was no
check that the number of arguments fits in that type.  This could result
in an invalid negative value being stored.

Check that the number of arguments does not exceed INT16_MAX.

Check that the number of arguments does not exceed INT16_MAX.

* [PATCH v1] Reject too many arguments in CREATE TRIGGER

The number of trigger arguments is stored as an int16, but there was no

Check that the number of arguments does not exceed INT16_MAX.

* [PATCH v1] Reject too many arguments in CREATE TRIGGER

The number of trigger arguments is stored as an int16, but there was no

in an invalid negative value being stored.

Check that the number of arguments does not exceed INT16_MAX.

* [PATCH v1] Reject too many arguments in CREATE TRIGGER

The number of trigger arguments is stored as an int16, but there was no

in an invalid negative value being stored.

Check that the number of arguments does not exceed INT16_MAX.

* [PATCH v1] Reject too many arguments in CREATE TRIGGER

The number of trigger arguments is stored as an int16, but there was no
check that the number of arguments fits in that type.  This could result
in an invalid negative value being stored.

Check that the number of arguments does not exceed INT16_MAX.

Check that the number of arguments does not exceed INT16_MAX.

* [PATCH v1] Reject too many arguments in CREATE TRIGGER

The number of trigger arguments is stored as an int16, but there was no

Check that the number of arguments does not exceed INT16_MAX.
