Yeah, that's the problem i mentioned with incorrect calculation of the 
PE reserve area.

If you command out line 663 in wine/loader/preload.c it should work 
again. ie. make it look like the following:

     vars.pe_size = 0x01000000;
     vars.pe_address = (void*)0x00400000;
//  wld_reserve_wine_memory( pe_file, &vars.pe_address, &vars.pe_size );
     mmap( vars.pe_address, vars.pe_size, PROT_NONE,
           MAP_FIXED|MAP_PRIVATE|MAP_ANON, -1, 0);
