Hello internals, today I have been pointed to bug #60982[1], which appears to be an unpleasant limitation. I wonder why the GC is not triggered when the memory limit is exhausted, what would avoid the script to end prematurely if there are uncollected cycles.
I've tried out a (maybe too simplistic) solution[2], and with that modification the test script of bug #69639[3] would run, as well as Dan Ackroyd's memTest.php[4] presented in the other bug report. With my limited knowledge of C, systems programming, and the Zend Engine in particular, I can't see any drawbacks with this modification, so I would be happy if more experienced programmers could point out crucial issues. Otherwise it might be worthwhile to investigate further improvements (I have not tackled zend_mm_realloc_heap() or even "Out of memory" conditions).
