ID: 28728 Updated by: [EMAIL PROTECTED] Reported By: steveh at brendata dot co dot uk Status: Wont fix Bug Type: DBX related Operating System: linux 2.4.28 PHP Version: 5.0.4 New Comment:
Just for the record (the follow-up will continue on pecl)... The following fixes the crash, but I'm not sure about side-effects so I won't consider it closed yet, which also means that I won't modify the dbx_sybasect.c source in cvs just yet. Feedback appreciated at http://pecl.php.net/bugs/bug.php?id=5398. Probable fix (verified that it doesn't crash, not tested for side-effects): Comment out (or remove) line 198 and 235 in dbx_sybasect.c: 198: zval_ptr_dtor(zv_name); 235: zval_ptr_dtor(zv_type); If you're using the source from pecl, the linenumbers are 204 and 242, respectively.

12:55:05] steveh at brendata dot co dot uk Ok, I've upgraded freetds to 0.62.4 >From the SQL Profiler I can see that the use and the select is being executed on the SQL server. I've successfully run tests using the tsql utility provided with freetds, I'm now at a bit of a loss as to what else to test, it looks like a fairly basic failure? The major difference is that this server is sql2000, whereas our production bugs server is sql6.5(!) ------------------------------------------------------------------------ [2004-06-14 12:16:49] steveh at brendata dot co dot uk Here's code that reproduces the issue along with the definition of the table (the table is currently empty). <?php function zsql_query($Sql) { $Link=dbx_connect(DBX_SYBASECT, "SALESTRACK", "SalesTracking", "sa", "password", DBX_PERSISTENT); $Result=dbx_query($Link,$Sql); dbx_close($Link); Return $Result; } function zdropdown($Variable,$QueryString,$Selected,$ExtraName="",$ExtraValue="",$SortColumn=2) { $Ret=""; $Result=zsql_query($QueryString." order by $SortColumn asc"); return $Ret; } echo zdropdown("dCM__DefaultInvoice_tblAddressID","select ID,Name from tblAddress",$dCM__DefaultInvoice_tblAddressID," ",-1); ?> I'm going to run some tests on freetds to make sure this isn't a freetds bug. ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
