Are you saying that I can modify ldo.c to address the issue? I only see one call to luaC_check(L) which is on line 396 in luaD_call. What exactly should I change?

Right now I'm just calling lua_gc(L, LUA_GCCOLLECT, 0) any time lua_pcall() returns an error. While probably horribly inefficient it does appear to address my issue.
