Fact · technical · confirmed
Both bugs are in the C engine, not in PHP code: the allocator's longjmp-based bailout on out-of-memory, and request globals that survive a failed request
The fix replaces bailout with a delayed error and an UnwindExit at a safe point, adds a hard limit that _exits, and resets the globals. See the code page.
Fact-check
A6 Established●●●●●● · Record · verdict: holds
The fix commit itself (read from a clone, raw patch hashed in the vault) says 'Replace bailout on OOM with UnwindExit' and 'Properly reset various globals that may be accessed during startup', and removes zend_bailout() from the allocator; the two advisories describe the same two mechanisms. The authoritative record carries it.
