r320726:
Expect :snprintf_float to segfault
This issue started occurring within the past month or so.
PR: 220502
Reported by: Jenkins (amd64-head job)
r320727:
:snprintf_float: don't blindly set RLIMIT_DATA and RLIMIT_AS to 1 MB -- raise
the limit to 32MB instead.
Require user=root and memory=64MB+ first so one can be reasonably sure that
the test will function appropriately.
