+// Regression test for a stack overflow in the TSX parser, found by fuzzing.
+//
+// `parse_jsx_element` recurses directly for every nested child element
+// (`<a><b><c>...`), but unlike the other recursive parse entry points it never
+// consulted the parser's stack guard. A source like `() => <div>` repeated
+// thousands of times nests that many `<div>` children (the `() =>` between each
+// pair is parsed as JSX text), so the unbounded recursion ran off the end of
+// the stack and the process died on the guard page with a bare SIGSEGV — no
+// crash handler, no error message.
+//
+// With the guard in place the parser stops and reports "Maximum call stack size
+// exceeded" instead of crashing. The transpile runs in a child process so a
+// regression fails these assertions rather than taking down the test runner.
