I have never seen such failure.<br>
<br>
But if you look at the the actual error message it looks like something<br>
very wrong is happening there. The test is supposed to write 64 bytes to<br>
the temporary file but it looks like in your case it attempts to write<br>
4294967295 bytes, which is around 4GB if I'm counting correctly so it's<br>
no wonder it fails with ENOSPC.<br>
<br>
My guess is that the test is miscompiled somehow but that is just a wild<br>
guess.<br>
