Some more information: I believe I've identified the culprit to be the 
luaC_checkGC() call introduced by item 6 of the 5.1.4 patches on 
http://www.lua.org/bugs.html. Just before the interpreter runs into the 
assertion failure this call sweeps the string table during the 
anchor_token() call in lparser.c:379. If I remove the checkGC() call my 
scripts run stable again.
