There is a very subtle bug in 5.0 alpha, that happens (sometimes) when a
userdata has a GC method stored in a weak metatable. The correction is
as follows:
--- lgc.c
*** 485,490 ****
--- 485,491 ----
separateudata(L); /* separate userdata to be preserved */
marktmu(&st); /* mark `preserved' userdata */
propagatemarks(&st); /* remark */
+ cleartablevalues(&st);
cleartablekeys(&st);
luaC_collect(L, 0);
checkMbuffer(L);
