Well, it appears there are more tokens that may lead to stack overflow, e.g. this particular crash happens with the following input:

$ cat clusterfuzz-testcase-6506407989084160 | xxd
00000000: 543d 543d 543d 543d 543d 543d 543d 543d  T=T=T=T=T=T=T=T=
00000010: 543d 543d 543d 543d 543d 543d 543d 543d  T=T=T=T=T=T=T=T=
00000020: 543d 543d 543d 543d 543d 543d 543d 543d  T=T=T=T=T=T=T=T=
<...>

Adding Token::EQUALS to the sanity check function helps to avoid crashing, but we are not sure whether it makes sense to do since the fuzzer future existence is questionable.
