[Wine]Unhandled exception: page fault

[Matthew L Reed]

I'm running hlds.exe, the windows Half-Life server. I've done this for 
several weeks with no problems at all. Tonight I see this:

WineDbg starting on pid 0x12
Unhandled exception: page fault on read access to 0x00000000 in 32-bit code 
(0x41742488).
In 32 bit mode.
0x400bd5eb strlen in libc.so.6: cmpg %ch.0x00(%eax)

I'm not quite sure what it is telling me. Is this a program crash of some 
sort, or does it indicate memory/disk error or some other type of hardware 
error?
