I already had report such bug. See bug #46055

Trying to fix it someway.

hymm..

just changing 

if (tidyRunDiagnostics(obj->ptdoc->doc) >= 0) {

to
	if (tidyStatus(obj->ptdoc->doc)!=0 && tidyRunDiagnostics(obj->ptdoc->doc) >= 0) {

? for 540rc1, fix works well

is tidyStatus() correct function here?

I guess it's ok to got with this approach.

743	int TIDY_CALL        tidyStatus( TidyDoc tdoc )
744	{
745	    TidyDocImpl* impl = tidyDocToImpl( tdoc );
746	    int tidyStat = -EINVAL;
747	    if ( impl )
748	        tidyStat = tidyDocStatus( impl );
749	    return tidyStat;
750	}


1117	int         tidyDocStatus( TidyDocImpl* doc )
1118	{
1119	    if ( doc->errors > 0 )
1120	        return 2;
1121	    if ( doc->warnings > 0 || doc->accessErrors > 0 )
1122	        return 1;
1123	    return 0;
1124	}

Hi, I did compile PHP 5.3.8 in August 2011 with not problems. Today (2012-01-13) 
compiling PHP 5.3.9 (with exact ./configure --...)
I had the next error:
/usr/bin/ld: /usr/local/lib/libtidy.a(alloc.o): relocation R_X86_64_32 against 
`a local symbol' can not be used when making a shared object; recompile with -
fPIC
/usr/local/lib/libtidy.a: could not read symbols: Bad value
collect2: ld returned 1 exit status
make: *** [libphp5.la] Error 1

I don't know about programming PHP Extensions (but a I'm a good php programmer).
I believe than these change affect Tidy compiling, Can you check?

Reopening since this patch made a regression.

e.g.
<?php
$t = new tidy('foo.html');
$t->cleanRepair();
var_dump($t->diagnose());
?>

printed bool(true) previously, but now prints bool(false).
(where foo.html is a file with no errors or warnings)

patch reverted with a test: http://news.php.net/php.cvs/67502

Did someone report this upstream to libtidy?
