+// Regression test for https://github.com/rust-lang/rust/issues/150898
+//
+// This test fails on Apple platforms with versions containing an allocator
+// bug. If this fails with SIGABRT, you may need to upgrade your system to
+// avoid other unexpected behavior.
+//
+// Note that the failure is non-deterministic so this test may pass even in
+// conditions where the bug is present. That being said, on the author's
+// machine this has a 100% rate of hitting the crash on at least a couple
+// threads.
+//
+// The bug was resolved by macOS 26.4.
