This bug still could be reproduced for 5.3.6/5.3.8 with 
bcompiler 1.0.2 for fuck.php in comments.

Please try the latest SVN revision, which should have this one fixed. If it works fine, please let me know and I'll close this bug.
 [2011-09-05 07:38 UTC] zhihong dot chen dot cn at gmail dot com
Many thanks for val.
Bug is confirmed fixed. 
Fuck.php can not break php anymore.
 [2011-09-05 07:39 UTC] val@php.net
This bug has been fixed in SVN.

In case this was a documentation problem, the fix will show up at the
end of next Sunday (CET) on pecl.php.net.

In case this was a pecl.php.net website problem, the change will show
up on the website in short time.
 
Thank you for the report, and for helping us make PECL better.
