5. InterBase: array handling [tests/007.phpt]

php: /usr/src/php-8.4.4/Zend/zend_hash.c:2736: zend_hash_internal_pointer_reset_ex: Assertion `(&ht->nInternalPointer != pos || zend_gc_refcount(&(ht)->gc) == 1) || ((ht)->u.flags & (1<<6))' failed.
Aborted (core dumped)

Termsig=6

1-4 all are in _php_ibase_alloc_xsqlda() allocating var->sqldata. This leakage should not be hard to track down and fix (I haven't been able yet though 😅)

5 is rather interesting. Some kind of bug passing arrays to Firebird array fields
