I’m still getting erroneous behaviour from my code when I exceed 2GB read / write buffers per process, so there may be something more to this.

I was alerted to the buf_idx[] overflow by a failing assert statement, which checks for overflow when assigning values to buf_idx[]. I'm running on lustre. I can't provide my current code as a test case. I may be able to prepare something later, but I need to focus on making my code work first.<br><br>These variables have type 'int', whereas something like 'size_t' or 'ADIO_Offset' might be more appropriate to store buffer offsets, where constraints are not known.<br><br>Sean<br><br><br>-----------------------<br><br>this is in the latest 3.1.3 MPICH? I thought I bumped up the size of <br>buf_idx and related fields, though my test cases are meager at best.<br><br>Do you have a test case?
