Hi, Alex.

Many thanks for reporting the issue and providing the patch. The patch looks simple. We will take it through testing, check if there are other similar cases and commit it to the code with an acknowledgment to you

When transferring large arrays (especially when using collective operations and complex types), problems like SIGSEGV or ABORT may appear due to integer overflow. I offer a patch to solve some situations. I am also attaching a small test that simulates one of the problems.
Regards, Alexander Melnikov.
