After calling a stored procedure that returns multiple resultsets, trying to call mssql_next_result causes PHP to coredump.

Reproduce code:
$this->RecordSet = mssql_query($query, $this->DBConn );
if(mssql_next_result($this->RecordSet)) {
    error_log("We got more results!");
} else {
    error_log("No more results.  Waah.");

Expected result:
I expect to see either "We got more results" or "No more results.  Waah." in the logs.

Actual result:
[Mon Nov 24 11:18:03 2008] [notice] child pid 5515 exit signal Bus error (10), possible coredump in /usr/local/apache2

Thank you for this bug report. To properly diagnose the problem, we
need a backtrace to see what is happening behind the scenes. To
find out how to generate a backtrace, please read for *NIX and for Win32

Once you have generated a backtrace, please submit it to this bug
report and change the status back to "Open". Thank you for helping
us make PHP better.

Well, I have a strange problem - when I turn --enable-debug on, the crash stops crashing - everything works as expected.  If I turn it off, it breaks again.  Without --enable-debug, I cannot create the backtrace.

Any chance you could provide some more information, such as: MSSQL version, query trying to execute, tables in a reproduce script that always fails.

Does this happen on other systems than Solaris, etc.
