Description Dirk Mueller 2006-02-19 21:28:54 UTC 
when ulimit package is installed, ulimit -v is set by default, and when done so, wine crashes immediately.
Comment 1 Marcus Meissner 2006-02-23 16:25:14 UTC 
can confirm.

I don't think you can. We are using MAP_NORESERVE, which could be
argued should not count against the limit, but if it does then we need
a limit high enough to reserve everything above 0x80000000.
