Bug ID: 44375
           Summary: High Virtual Memory crashing many 32bit games.
           Product: Wine
           Version: unspecified
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: major
          Priority: P2
         Component: -unknown

I've been noticing this in many games although could never confirm where the
issue was coming from, many games would just crash after a period of time.

Recently been investigating this issue and it seems to affect a lot of titles.
The games in question would work perfectly until at some point they will just
crash with an error.

The worst ones so far are - Legend of Grimrock 2 and Race Driver: GRID

Meanwhile there are the ones which will work fine (sometimes even a couple of
hours), then crash when they reach 4GB Virtual Memory used, examples are:

Path of Exile
Dragon Age: Origins
NecroVisioN

It is worth noting that reducing the graphics details also reduces the amount
of virtual memory used and prolongs the crash.

I noticed another old bug report such as this:
