Hi Hans,

These tests crash on Vista with .NET 3.5 (not sure about other platforms/.NET 
versions yet). The enum_gac_assemblies function relies on the fact that 
ffd.cFileName contains 2 underscores. On Vista however I see some assemblies 
with a different format for the cFileName like:

6.0.0.0_en_31bf3856ad364e35

This explains the (first) crash as we dereference a pointer. So doing something 
like this fixes that piece:

          else if (depth == 1)
          {
-            ptr = strstr(ffd.cFileName, "__");
+            CHAR version[MAX_PATH];
+
+            lstrcpyA(version, ffd.cFileName);
+            ptr = strstr(version, "_");
              *ptr = '\0';
-            ptr += 2;
+            ptr = strrchr(ffd.cFileName, '_');
+            ptr += 1;
              sprintf(buf, "Version=%s, Culture=neutral, PublicKeyToken=%s",
-                    ffd.cFileName, ptr);
+                    version, ptr);

This seems to work fine but than it crashes again while trying to free the 
memory "HeapFree(GetProcessHeap(), 0, asmname->data);" in test_enumerate.

Just ignoring those HeapFree's doesn't fix it as we crash again later on.

Yes, that test simply ignores the culture attribute. Is that one of your
own machines? If so, can you try this patch?

At least we don't crash at that point (but still at the HeapFree). The patch is 
not correct however as tracing shows in some cases:

Culture=en_31bf3856ad364e35

(and that makes sense reading the patch ;) )

The second crash (HeapFree) is because we use strdup. Looks like on Windows 
strdup doesn't allocate memory on heap.

I guess we should replace strdup by a HeapAlloc/lstrcpyA ?
