Log:
  :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.

Comment 3 Enji Cooper freebsd_committer freebsd_triage 2017-07-06 08:12:10 UTC 
I suspect the segfault was either happening due to the ino64 project's increased footprint requirement or the jemalloc upgrade. Nevertheless, the test should have been more robust.
Comment 4 Konstantin Belousov freebsd_committer freebsd_triage 2017-07-06 09:08:41 UTC 
(In reply to Ngie Cooper from comment #3)
So does the test pass now, with the resource limits increased ?  Or there is something further to look at ?
Comment 5 Eitan Adler freebsd_committer freebsd_triage 2018-01-08 04:14:47 UTC 
For the following conditions
Product: Base System, Documentation Status: New, Open, In Progress, UNCONFIRMED 
Assignee: Former FreeBSD committer 

Reset to default assignee. Reset status to "Open".
