Dear Open MPI community,
I'm a member of MPI library development team in Fujitsu,
Takahiro Kawashima, who sent mail before, is my colleague.
We start to feed back.
First, we fixed about MPI_LB/MPI_UB and data packing problem.
Program crashes when it meets all of the following conditions:

Dear all,
We send next feed back.
It's about C++ header file.
In ompi/mpi/cxx/*.h,
Some definitions of return code, type and function are lacked or incorrect.
Attached patch fixes them (This Patch is for V1.4.X).
Following list is what is lacked and incorrect.

Dear Jeff and all,
Thank you for your comment.
I'm sorry for not replying sooner.

Dear All,
Next feed back is about MPI_Gather problem.
Gather may be truncated in following condition:
1:ompi_coll_tuned_gather_intra_linear_sync is called.
(message size is over 6000B)
2:Either send data type or recv data type is derived type and
other data type is predefined data type.

Dear All,
Next is question about "MPI_Close_port".
According to the MPI-2.2 standard,
the "port_name" argument of
MPI_Close_port() is marked as 'IN'.
But, in Open MPI (both trunk and 1.4.x), the content of
"port_name" is updated in MPI_Close_port().
It seems to violate the MPI standard.
The foll
Dear All,
Next is about "MPI_FILE_SEEK_SHARED" in Fortran.
When MPI_FILE_SEEK_SHARED is called in Fortran Program,
the shared file pointer is not updated.
Incorrent function call is the following part:
ompi/mpi/f77/file_seek_shared_f.c---

Dear All,
We found some typos in error code/func_name/man.

Dear All,
Next feedback is "MPI_Comm_spawn_multiple".
When the function called from MPI_Comm_spawn_multiple failed,
Segmentation fault occurs.
In that condition, "newcomp" sets NULL.
But member of "newcomp" is referred at following part.

Next feedback is about "coll_tuned_dynamic_rules_filename".
Incorrect algorithm is selected in following conditions:

Dear All,
Next feedback is about "collective communications".
Collective communication may be abend when it use over 2GiB buffer.
This problem occurs following condition:
-- communicator_size * count(scount/rcount) >= 2GiB
It occurs in even small PC cluster.
