You obviously do not have the correct sources then.
Try get them directly using SVN:
# svn co http://svn.php.net/repository/php/php-src/branches/PHP_5_2/
And if those don't work either, you need to provide a GDB backtrace, the
strace is useless for this. Also make sure you configure PHP using
--enable-debug !!
I have compile both apache and php using debug and run gdb with the
following result:

The function custom_open_base_check() contains:
// Document root from Zend (pointer to pointer)
zval **document_root = NULL;
// Make sure DOCUMENT_ROOT is accessible from the global vars
if (!PG(http_globals)[TRACK_VARS_SERVER] ||
zend_hash_find(PG(http_globals)[TRACK_VARS_SERVER]->value.ht,
"DOCUMENT_ROOT",
sizeof("DOCUMENT_ROOT"), (void **) &document_root) == FAILURE) {
// Unable to find DOCUMENT_ROOT
php_error_docref(NULL TSRMLS_CC, E_WARNING,
"fopen_wrapper_patch: DOCUMENT_ROOT variable
is not set, cannot determine document root.");
// Can't check the document root - fail
return -1;
}
It crashing when its looking up the DOCUMENT_ROOT in the
zend_hash_find. This only occurs when the following is defined in an
.htaccess and with the custom function in place:
[snip]
php_value error_log '/home/st/stu/studio1.com.au/www/logs/php_err.log'
Is it safe to access the DOCUMENT_ROOT this way at this point in the
code? If not is there an alternative or is there something wrong
somewhere else in the code?
If you could guide me on how to produce the necessary output to debug
it would be much appreciated.
Thanks
