This problem is caused by ill-formed utf-8 handling issue of libmbfl.
libmbfl is maintaining at https://github.com/moriyoshi/libmbfl.
Please try to use the newest version of libmbfl on github.

I can reproduce that on windows too, the issue is probably not only osx. Here's
slightly modified snippet:
?php
$str1 = \xF0\xA4\xAD . \xF0\xA4\xAD\xA2 . \xF0\xA4\xAD\xA2;
$exp1 = \xEF\xBF\xBD . \xF0\xA4\xAD\xA2 . \xF0\xA4\xAD\xA2;
if (true !== mb_substitute_character(0xFFFD)) {
die(can't set substitute char\n);
}
print_hex($str1);
$s = mb_convert_encoding($str1, 'UTF-8', mb_detect_encoding($str1));
print_hex($s);
function print_hex($s)
{
for ($i = 0; $i strlen($s); $i++) {
echo 0x, dechex(ord($s[$i])), ;
}
echo \n;
}
?
And the output (added pipes as utf8 char separators manually)
0xf0 0xa4 0xad | 0xf0 0xa4 0xad 0xa2 | 0xf0 0xa4 0xad 0xa2
0xef 0xbf 0xbd | 0xef 0xbf 0xbd | 0xef 0xbf 0xbd | 0xef 0xbf 0xbd | 0xf0 0xa4
0xad 0xa2
As one can see, the first original invalid 3 byte sequence and the second valid
4 byte sequence are replaced with 0xef 0xbf 0xbd, the last one remains.
However looking at the codes only libmfl is in the game
there http://lxr.php.net/xref/PHP_5_5/ext/mbstring/mbstring.c#3011 . Not sure
yet to have overseen something, have to make a C
snippet.

Description:
When converting string from UTF-8 to UTF-8 by using mb_convert_encoding for
replacing ill-formed byte sequence with the substitute character(U+FFFD),
mb_convert_encoding replaces the character follwing ill-formed byte sequence
with
the substitute character. mb_convert_encoding also delete trailing ill-formed
byte
sequence and doesn't replace it with the substitute character.
The comprehensive test case for 2-4 byte
characters is here: https://gist.github.com/masakielastic/5793665 .
Test script:
---
// U+24B62: \xF0\xA4\xAD\xA2
// ill-formed: \xF0\xA4\xAD
// U+FFFD: \xEF\xBF\xBD
$str = \xF0\xA4\xAD. \xF0\xA4\xAD\xA2.\xF0\xA4\xAD\xA2;
$expected = \xEF\xBF\xBD.\xF0\xA4\xAD\xA2.\xF0\xA4\xAD\xA2;
$str2 = \xF0\xA4\xAD\xA2.\xF0\xA4\xAD\xA2.\xF0\xA4\xAD;
$expected2 = \xF0\xA4\xAD\xA2.\xF0\xA4\xAD\xA2.\xEF\xBF\xBD;
mb_substitute_character(0xFFFD);
var_dump(
$expected === htmlspecialchars_decode(htmlspecialchars($str,
ENT_SUBSTITUTE, 'UTF-8')),
$expected2 === htmlspecialchars_decode(htmlspecialchars($str2,
ENT_SUBSTITUTE, 'UTF-8')),
$expected === mb_convert_encoding($str, 'UTF-8', 'UTF-8'),
$expected2 === mb_convert_encoding($str2, 'UTF-8', 'UTF-8')
);

I've just been bitten by this bug too.
It manifests as Connection Reset error on the website, and this in the apache
logs: [Sun Jun 30 20:58:07 2013] [notice] child pid 32544 exit signal
Segmentation fault (11)
I do understand that the segfault isn't a PHP bug, but it would be really
helpful if the error message could be more specific: something like segfault
in PCRE at line X in file Y.
Aside: another test-case.
Here, it can be triggered by a value over about 5400:
$input='span'.str_repeat('X', 5500).'/span';
$output = preg_replace(/span(((?!(\/span)).)*)\/span/, BEGIN \\1 END
,$input);
If I reduce pcre.recursion_limit converts the segfault into a PCRE failure...
but there is nothing that will make the RE actually work as intended. (in the
contrived example, we can of course just use str_replace).

We have no control over the segfault, if we would, it would happen in the first
place.
You can play with the stack size (apache config), increase it and at some point
it
will be large enough to avoid this crash.

Birmingham +52.4800 -1.9100 London +51.5171 -0.1062 Bristol +51.4600 -2.6000 There are 7 cities in the heap There should be the same number of city nodes in the heap after iterating through as there were before.
