           Product: Wine

          Platform: PC
        OS/Version: Linux
            Status: UNCONFIRMED

Hi there,

I wanted to make some D3D/DDraw tests with the demo version of Shiny's
Sacrifice on a system where I don't have root access.

The problem is that the system has 512MB physical memory installed and 8GB of
swap configured. This is too much for Sacrifice and seems to trigger an (32bit
?) integer overflow.

The error message from Sacrifice is:
"Insufficient pagefile space. Please ensure that virtual memory is enabled and
that you have more than 128MB of disk space free on your pagefile drive before
running Sacrifice."

I did a search on Google for that problem and it also appears on Windows if the
system has a large amount of memory (or swap) installed, that triggers the
overflow.

So I was going to use ulimit -v to restrict memory usage by wine, but that does
not seem to work:

user at yui09:~/.wine/drive_c/Program Files/Shiny/Sacrifice Demo$ wine
"Sacrifice.exe"
preloader: Warning: failed to reserve range 00000000-60000000
wine: failed to initialize: /homes/user/local//lib/wine/ntdll.dll.so: failed to
map segment from shared object: Cannot allocate memory

I have tried values for ulimit -v of 64MB, 128MB, 256MB and up to 2GB. Always
the same problem with the preloader and the failed initialization.

Wine doesn't seem to respect the limits set by ulimit. I would really like to
make some tests on this system. Maybe someone can take a look at this ulimit
problem?

Greetings from Germany,
Tobias Jakobi
