From 201972ac4cf81d12a7018308b9e88400c5e61a9d Mon Sep 17 00:00:00 2001 From: rhe Date: Wed, 14 Dec 2016 12:32:42 +0000 Subject: encoding.c: handle needmore error from rb_enc_precise_mbclen() rb_enc_ascget() erroneously reports success even if the given byte sequence is incomplete, for non-ASCII compatible encoding strings. rb_enc_precise_mbclen() may return a negative value on error, and thus rb_enc_ascget() must not store the return value in 'unsigned int'; otherwise the subsequent MBCLEN_CHARFOUND_P() check won't catch the error.
