Issue #13034 has been reported by Kazuki Yamaguchi.
----------------------------------------
Bug #13034: rb_enc_ascget() does not handle 'needmore' error from rb_enc_procise_mbclen()
https://bugs.ruby-lang.org/issues/13034

* Backport: 2.1: UNKNOWN, 2.2: REQUIRED, 2.3: REQUIRED
----------------------------------------
rb_enc_ascget() stores the return value from rb_enc_procise_mbclen() that may return a negative value on error to 'unsigned int', and thus it overlooks errors due to incomplete UTF-16/32 byte sequence.
This bug is visible from Ruby; for example, the following code gets stuck in infinite loop:
~~~
str = "\x00".force_encoding("UTF-16BE")
Regexp.quote(str) # Ruby freezes
~~~
