I'm seeing what could be related if not the same problem trying to
detect trailing windows CR+LF in T_WHITESPACE:
Reproduce code:
---------------
<?php
// this comment and trailing blank contain windows CR+LF^M
^M
Expected result:
----------------
array(3) {
[0]=>
array(3) {
[0]=>
int(367)
[1]=>
string(6) "<?php
"
[2]=>
int(1)
}
[1]=>
array(3) {
[0]=>
int(365)
[1]=>
" string(57) "// this comment and trailing blank contain windows
CR+LF
[2]=>
int(2)
}
[2]=>
array(3) {
[0]=>
int(370)
[1]=>
string(3) "
"
int(2)
}
}
[2]=>
int(2)
}
}
Actual result:
--------------
array(2) {
[0]=>
array(3) {
[0]=>
int(368)
[1]=>
string(6) "<?php
"
[2]=>
int(1)
}
[1]=>
array(3) {
[0]=>
int(366)
[1]=>
" string(57) "// this comment and trailing blank contain windows
CR+LF
[2]=>
int(2)
}
}

this is a problem in the new lexer. The problem is reproduceable if
after the comment there's the EOF (with no \n after the comment).
This, again, is triggered because of the difference in handling the EOF
between flex and re2c..
A simple hack would be to detect the ST_ONE_LINE_COMMENT state on EOF
and return the correct value, but I would prefer a more general thing.

Description:
------------
When using the tokenizer to lex given text, the output seems to miss
the last token, if it was a single line comment.
It only seems to occur if there isn't a newline behind the comment
lexeme.
Note the last entries in the arrays.
Reproduce code:
---------------
<?php
print_r(token_get_all(file_get_contents(__FILE__)));
// test
$var = 5;
// test
Expected result:
----------------
