I'm also suffering from this issue. I had phpunit randomly crashing. Traced the
problem using xdebug - I'm using the Database YAML extension
(PHPUnit_Extensions_Database_DataSet_YamlDataSet), and it uses the include
statement to load the YAML files.
The YAML file knocking everything over was exactly 8192 bytes long (and ended
with whitespace, but not \n).

This is actually a good hint by hanssen at aeteurope dot nl: I too had some cases
where a generated cache file (containing "<?php $data = var_export(...)") would
crash PHP when it was exactly 4096 Byte in size.

I experience an issue which I think is caused by the same bug (PHP crashes in line 3182 of
Zend/zend_language_scanner.c (contains "if ((yych = *YYCURSOR) == '\n') goto
yy203;", part of function lex_scan()).
In my case I call php_strip_whitespace() on a PHP file with a length of exactly 4096 bytes (the same
length as the problem file reported by the original author of this bug) and where the file ends with
"?>" without trailing newline.
Inspection of lines 3181 and 3182 of Zend/zend_language_scanner.c reveals YYCURSOR being advanced
one byte and a '\n' being expected, which fails here because it attempts to read memory
beyond allocated memory.

I also have php crashes - win7 64, apache 2.2.21 from apache lounge.
No error messages left in either php or apache logs - just a "server reset connection"
error from the browser.
The code ran fine up to php 5.3.8 (did not test with 539).
It involves executing a custom page within eZPublish, it is hard for me to trace it to a single php
file / command and attach it here...

Ah you already did. Which EOL do you use on your original script? Unix or windows
ones?
Maybe zip it and post a link to the zip file, so the contents won't be altered
(lexer bug).
