Regression: AOT ArrayObject::getIteratorClass()/getIterator() aborts — VM/JIT match Zend (re-#18185, ext/spl/spl_array.c) #27567
Description

Regression · php-src-strict · AOT
Problem
new ArrayObject($arr, 0, MyIter::class) must report getIteratorClass() === MyIter and getIterator() must return a MyIter instance. Zend/VM/JIT print gic=MyIter / cls=MyIter and iterate; AOT prints empty gic= then aborts (SIGABRT, exit 134). Prior closed issues (#18185 / #10639) fixed VM — AOT still broken. Verified @ 0392e7d24 (2026-08-04).

Merged — AOT ArrayObject getIteratorClass/getIterator now match Zend/VM (
gic=MyIter/cls=MyIter/0=1 1=2).Batch complete this run: #27422, #27312, #27567 merged.
