DosQueryModuleHandleStrict() loops forever and drains stack

Description
Due to bugs in the DosQuerySysState API, the returned buffer seems to contain circular references under some (quite random) conditions. This makes the walkModules() worker (used by DosQueryModuleHandleStrict()) recurse into itself until it eats up all the stack.
From the user perspective, this looks like an application giving 100% CPU load for some tens seconds and then crashing with SYS1808.

Fixed in r21579. Turned out to be a tiny typo (lost break statement), not yet another DQSS bug. Which is even better.
Note:
See TracTickets
for help on using tickets.
Note that the issue usually goes away on its own after starting several other applications to cause the list of DLLs loaded into memory to change (which seems to eventually break the circuit).
