Thank you for this bug report. To properly diagnose the problem, we
need a short but complete example script to be able to reproduce
this bug ourselves. 

A proper reproducing script starts with <?php and ends with ?>,
is max. 10-20 lines long and does not require any external 
resources such as databases, etc. If the script requires a 
database to demonstrate the issue, please make sure it creates 
all necessary tables, stored procedures etc.

Please avoid embedding huge scripts into the report.

Could you provide me a complete script to reproduce your issue and an explanation 
of the problem ? When does it occur ? The current bug description is not explicit 
at all.

Thanks

I try to give you as many information as i can.

mqseries_open TEST_QM error with CompCode:2 Reason:2044 Text:Object descriptor 
structure not valid.

In /opt/mqm/inc/cmqc.h

I don't know if it has any bad effect with this macro:

#define MQSERIES_SETOPT_LONG(s,m) \
    if (zend_hash_find(ht, #m, sizeof(#m), (void**)&tmp) == SUCCESS) {\
        convert_to_long(*tmp); \
        s->m = Z_LVAL_PP(tmp); \
    }

I tried to reproduce your bug on my local but was not able to. What version of 
MQseries are you using ? Did you tried to use the latest version from git ? Or 
tried to update your PHP ? If you have any clue on how I can make this bug appear 
on my side I'll be glad to help you.

No feedback was provided. The bug is being suspended because
we assume that you are no longer experiencing the problem.
If this is not the case and you are able to provide the
information that was requested earlier, please do so and
change the status of the bug back to "Open". Thank you.

I too have the same segfault problem at mqseries_close.  Here's my environment:

I am getting the same error on my dev environment using --with-libdir=lib64 with the default put code included in the example directory.
