On systems with limited memory and that are compiled with debugging information, this particular test is causing OOM condition especially as it is run in parallel. Even when run with a stripped binary as an input, the test consumes upward of 250M RSS. By limiting the input stream to the 1M, the stream is still buffering but memory consumption is similar to other parallel tests.
