Adds a test for the segfault in #10221.
Like @JeffBezanson and @carnaval, I found that when run as part of a script I needed the
versioninfo()
call, and am redirecting stdio to suppress output. (For whatever reason,versioninfo(IOBuffer())
did not trigger the segfault.) I remember some rare Travis failures in conjunction with #8251, which also used I/O redirection, so I suppose there is some risk here (hence the PR). But I also wonder if those might have been due to the interesting observations made by @garrison in #10218.
