Facing issue with test JsonStreamParserTest.ObjectValues on big-endian system,

Any idea on following error:

I don't think we actively test on any big-endian machines, so it wouldn't be surprising if there are a few bugs that come up in that environment. We would welcome any pull requests with bug fixes.

protobuf-test is failing with segmentation fault after execution of test sonStreamParserTest.ObjectValues.
Please find the log attached for the same.

I have observed that the if the string used in testcase is reduced to 149 characters the testcase observed passing.

Any comments to debug on this would be useful and wanted to know the importance of this test.
