New Comment:
Doing some more investigation:
if the "ending" is just a character, the function works fine and return
the correct value, always.
stream_get_line in ./ext/standard/streamfuncs.c passes the action to
php_stream_get_record in ./main/streams/streams.c where there is an
explicit condition:
if delim_len == 1 the result is directly fetched using memchr() else
php_memnstr() is requested to process the stream.
./main/php.h defines php_memnstr as zend_memnstr, and looking at
./Zend/zend_operatprs.h the function zend_memnstr uses memchr() and
memcmp() and I should suspect something going wrong there.
The patch that sometimes forces the function to work correctly is a
proof that all these functions work correct but there is a variable
whose value is not being set correctly, ie not being initialized
(maybe?)
Anyway, this function is a very useful one and it's really unfortunate
that it has not been fixed in almost 5 months.

I just got PHP 6.0.0-dev (built: Jul 28 2008 02:06:04) also configured
and installed. that too has this problem of not working correctly.

I should also add that the workaround (that works for this example
file) does not always work.

Also tried with the latest CVS snapshot of 5.2.7-dev and it still gives
incorrect results.

Tested this with PHP v5.2.6 on Windows 2008 Server and FreeBSD 7.0 and
it still returns incorrect results.
