Describe the problem you're observing

The recently added send-c_volume test case fails occasionally on 32-bit systems. The failure is the result of the stream size not matching the expected dataset size. However, the behavior here isn't consistent and the test case often passes.

Test: tests/functional/rsend/send-c_volume (run as root) [00:08] [FAIL]

Describe how to reproduce the problem

The issue is more likely to manifest itself in the buildbot test environment.
