Hi,
we still waiting for the fix.
Sometimes we must restart the web server and this is causing some
problems to the users and mainly for our customers. What to say to the
customers when web server stops sometimes regarding a php error ?
I got more info if can help.
The problem happens not only when the procedure receives null
parameters for non null arguments.
If, in a procedure code, for example, I create a temporary table and it
have fields that does not accept null values and, when inserting rows
with null values into non null fields, the same problem happens. PHP
stops the web server. Sybase just returns error (-6) advising that the
field does not accept null values ...
We know that this is a error on the logics of the procedure and can be
fixed by the programmer, fixing the code and recompiling the procedure
and so on.
We know that you are doing the best, but on my single oppinion, it's a
problem to be fixed urgently.
Are there any news about this bug fix ?
Thanks again.

Have been able to reproduce with sybase libraries. As these are not
available on FreeBSD, I use FreeTDS, which does not produce a status
result in this situation ("return status = -6") but rather issues a
"CS_CMD_FAIL" instantly. I know where the problem is
(php_sybase_finish_results), fixing it is not trivial though (I've
already given it a first shot but gave up after the supposed fix caused
a segfault in another place:)). I'll do my best and see if I can
include the fix in 4.3.2.

Bingo !
The output is below:

>>> Query: exec tempdb..test
*** Caught Sybase Server Message #201 [Severity 16, state 2] at
line 0
'Procedure test expects parameter @param, which was not supplied.'
PHP has encountered an Access Violation at 01EB36C9
At this point the PHP stopped and IIS too, exactly as we have posted.
It was necessary to stop and restart the www service manually.
Thanks again for your great help.
