Builds on sparc64 repeatedly failed on tests main.ctype_binary
main.ctype_latin1 with error message:

This indicates that the code path in these two tests are able to crash
the server.

These two tests were passing in the 10.11.4-1 builds in Debian
unstable, so this is clearly a regression in 10.11.5.
