Re: [Openwbem-devel] CMPI issue

It looks like the enumInstanceNames pointer is null which is the direct cau=
se of your crash. The real problem though is with whatever set it to null, =
since it shouldn't be null, it should be pointing to the mbEnumInstanceName=
s function. It also looks like the brokerVersion and brokerName are also in=
correct. Probably something overwrote memory and clobbered the bft table. Y=
ou could try using valgrind, it may point you to the culprit.

Subject: [Openwbem-devel] CMPI issue

Hi,
I am working on the CMPI providers for OpenWBEM. I have two providers A and=
 B.
Whenever I try to invoke enumInstanceNames of Provider B from an extrinsic =
method of Provider A, it results in segmentation fault. Although, when enum=
InstanceNames of B is invoked from any CIM Client, it is always successful.

While debugging the problem with gdb, I am getting following trace:

166             en =3D broker->bft->enumInstanceNames(broker, ctx, oPath, r=
c);
(gdb) p *broker->bft

Plz share your inputs for resolving this problem.
