I found the problem. The sanitiser execution tests produce a lot of output (~20KB on stderr). Somtimes, when EOF is matched in standard_wait, there are unmatched characters left in the expect buffer. These need to be appended to $output. This has probably escaped us until now because execution test output has been very short.
I'll do some more testing before checking this in.
Cheers,

* lib/remote.exp (standard_wait): Append any trailing characters
to $output that may be still in $expect_out(buffer) when eof is
matched. Remove arbitrary limitation in the ".+" matching case,
similar to the change to local_exec on 2016-02-17.
