Siegmar and all,
i am puzzled with this error.
on one hand, it is caused by an invalid buffer
(e.g. buffer size is 1, but user suggests size is 2)
so i am fine with current behavior (e.g.
java.lang.ArrayIndexOutOfBoundsException is thrown)
/* if that was a C program, it would very likely SIGSEGV, e.g. Open MPI
does not catch this kind of error when checking params */
on the other hand, Open MPI could be enhanced to check the buffer size,
and throw a MPIException in this case.
as far as i am concerned, this is a feature request and not a bug.
thoughts anyone ?
Cheers,
Gilles

Hi,
I have installed v1.10.3-31-g35ba6a1, openmpi-v2.0.0-233-gb5f0a4f,
and openmpi-dev-4691-g277c319 on my "SUSE Linux Enterprise Server
12 (x86_64)" with Sun C 5.14 beta and gcc-6.1.0. In May I had
reported a problem with Java execeptions (PR 1698) which had
been solved in June (PR 1803).

Unfortunately the problem still exists or exists once more
in all three branches.

I would be grateful, if somebody can fix the problem. Thank you
very much for any help in advance.
