I guess it's time to write a testcase.

The patch I tried earlier was in wcmdmain.c:
-            if (assumeInternal || context || !HIWORD(console))
WaitForSingleObject (pe.hProcess, INFINITE);
+            if (opt_c || opt_k || assumeInternal || context ||
!HIWORD(console)) WaitForSingleObject (pe.hProcess, INFINITE);
but it didn't keep devenv from crashing.
