I ran the test overnight in a loop on a 64 bit system.

The first 36 runs were fine.  
The 37th run failed, but without a crash:

../../../tools/runtest -q -P wine -M wininet.dll -T ../../.. -p
wininet_test.exe.so urlcache.c && touch urlcache.ok
fixme:wininet:CommitUrlCacheEntryInternal entry already in cache - don't know

urlcache.c:699: Test failed: GetUrlCacheEntryInfo failed with error 2
urlcache.c:712: Test failed: DeleteUrlCacheEntryA failed with error 2

The next six runs all failed with the earlier crash (but the wrong 
dwStructSize is a different garbage value):

../../../tools/runtest -q -P wine -M wininet.dll -T ../../.. -p
wininet_test.exe.so urlcache.c && touch urlcache.ok
