EventVwr does not show all events after "Clear all" and finally corrupts the Event file

reactos-bootcd-0.4.15-dev-5130-gc1c1279-x86-gcc-lin-dbg

• Open Event Viewer
• Clear all System Content
• Open Service Manager Start then Stop "ReactOS Installer Service", same for "Themes

and logs shows

err:(dll/win32/rpcrt4/ndr_marshall.c:6540) value exceeded bounds: 5177428, low: 0, high: 524287

err:(dll/win32/rpcrt4/rpc_message.c:1878) we got fault packet with status 0x1c000007

Adding more events (start/stop services,...) leads items to be added but not listed upon refresh :

• Repeat the operation and you'll finally have a corrupted file :
