Bug description:Incorrect line endings causes segfault in
convert.quoted-printable-encode
Description:
------------
When using the convert.quoted-printable-encode stream filter, if the stream
contains a single bare CR line ending at the end of the stream when
line-break-chars is set to CRLF this can cause a segfault with certain
values of line-length.
Changing the line-length in the test script, or setting line-break-chars to
"\r" prevents the segfault.
Test script:
---------------
$data = fopen('php://temp', 'r+');
fwrite($data, "test\r\ntest\r\n\r");
$stream = fopen("php://temp", 'r+');
stream_filter_append($stream, 'convert.quoted-printable-encode',
STREAM_FILTER_WRITE, array('line-length' => 5, 'line-break-chars' =>
"\r\n"));
rewind($data);
stream_copy_to_stream($data, $stream);
Expected result:
----------------
The data should be copied from the $data stream to the $stream stream,
applying the convert filter.
Actual result:
--------------
Segfault.
