Component:  ports    |    Version:  2.8.1
 Keywords:           |       Port:  rust
---------------------+---------------------------------
 The only obvious failure in the buildbot logs, occurs at very end.

 Unfortunately, there doesn't appear (?) to be any other detail, apart from
 the following nebulous error:

 {{{
 Finished dev [unoptimized] target(s) in 1m 20s

 thread 'main' has overflowed its stack
 fatal runtime error: stack overflow
 }}}
