[php-src] Issue #8079: Recent patch to SplFixedArray causes array_walk + json encode to hang, circular var_export during gc to run out of memory

Issue: https://github.com/php/php-src/issues/8079 Comment Author: TysonAndre > If it recreates properties table on each call to > get_properties() let it protects from recursion itself. SplFixedArray doesn't have a way to tell if the properties table (whether from get_properties/get_properties_for) is still in use, though, so I don't know how you'd make it protect from recursion without changing the engine (with var_export/debug_zval_dump, infinite recursion detection only works if the returned table is the same instance every time) What solution did you have in mind? ----- Also, if a solution can't be found, I think we should revert 52ae6417ca3e62eff796bf3e3b5662fe6a9ee085 Fixed GH-8044 (var_export/debug_zval_dump HT_ASSERT_RC1 debug failure for SplFixedArray) in 8.0+ to avoid introducing new bugs in 8.0/8.1 such as out of memory errors during gc (before the next RC/patch releases) - I consider the original bug much, much less severe
