I found that only with magic_quotes_sybase on did the error occur.  I
was then able to work around it. I will try the cvs snapshot tomorrow
and let you know what happens.

Please try using this CVS snapshot:

  http://snaps.php.net/php4-STABLE-latest.tar.gz
 
For Windows:
 
  http://snaps.php.net/win32/php4-win32-STABLE-latest.zip

Works fine in win32 using latest CVS snapshot..

Description:
------------
returns an error of 
Parse error: parse error, unexpected T_CONSTANT_ENCAPSED_STRING in
C:\Documents and Settings\john\Desktop\ttms
desktop\php\gui\Smarty_Compiler.class.php(288) : regexp code on line 2


Reproduce code:
---------------
$ldq = preg_quote('{', '!');
$rdq = preg_quote('}', '!');
$search =
"!{$ldq}\*(.*?)\*{$rdq}|{$ldq}\s*literal\s*{$rdq}(.*?){$ldq}\s*/literal\s*{$rdq}|{$ldq}\s*php\s*{$rdq}(.*?){$ldq}\s*/php\s*{$rdq}!s";
$source_content = preg_replace($search.'e', "'"
                                       . '{' . 'php'
                                       . "' . str_repeat(\"\n\",
substr_count('\\0', \"\n\")) .'"
                                       . '}'
                                       . "'",
                                       "a
{literal}b{/literal}c{php}d;s{/php}e{* hello's *}");


Expected result:
----------------
a{php}c{php}e{php}

Actual result:
--------------
Parse error: parse error, unexpected T_CONSTANT_ENCAPSED_STRING in
C:\Documents and Settings\john\Desktop\ttms desktop\php\index.php(17) :
regexp code on line 2

Fatal error: Failed evaluating code: '{php' . str_repeat(" ",
substr_count('{* hello''s *}', " ")) .'}' in C:\Documents
and
Settings\john\Desktop\ttms desktop\php\index.php on line 17
