Bug description:doc comments picked up from previous scanner run
Description:
------------
The doc_comment compiler global is not reset when scanning of a new
file/string
starts. This leads to the last doc_comment seen by the tokenizer, but
unclaimed
by anything, being incorrectly assigned to the next thing the compiler
sees.
I think that the doc_comment and doc_comment_len globals should probably be
saved/restored by zend_(save|restore)_lexical_state, and reset whenever
scanning
for a new file or string starts (pretty much everywhere zend_lineno gets
initialised.)
Test script:
---------------
token_get_all("<?php\n/**\n * Foo\n */"); // doc_comment compiler global
now contains this Foo comment
eval("class Foo { }"); // Could also be an include of a file containing
similar
$rc = new ReflectionClass("Foo");
var_dump($rc->getDocComment()); // Foo shouldn't have a doc comment, and
yet it does.
Expected result:
----------------
bool(false)
Actual result:
--------------
string(14) "/**\n * Foo\n */"
