The intern instruction has been incorrectly marked leaf=true for a long time (3.3 through trunk) and its stack canary check crashes the whole runtime process.

The crash reliably happens in debug builds. (VM_CHECK_MODE > 0)

In release builds it can give the wrong line number in backtrace, if running in the interpreter, or when running in the JIT cause GC memory safety issues.
