Subject: Fix wrong storage of data when hex-style string is loaded

This patch fixes corruption of data when hex-style string is
loaded.

I saw following phenomenon in an ubuntu/amd64 environment.

Test code:
str = "\x0\x1\x2\x03\x04\x05\x06\a\b\t\n\v\f\r\x0E\x0F\x10"
p str[-1] == "\0x10"

Output(binary program with mrbc -B):
false

Output(script with mruby):
true
