Is it possible to you to "instrument" this call, so you can see what
it is marking? You could put a printf in both loops, more or less like
this (not tested):
- for (o = l->stack; o < l->top; o++)
- markvalue(g, o);
- for (; o <= lim; o++)
- setnilvalue(o);
+ for (o = l->stack; o < l->top; o++) {
+ if (NOW) printf("marking %d\n", o->gch.tt);
+ markvalue(g, o);
+ }
+ for (; o <= lim; o++) {
+ if (NOW) printf("erasing %d\n", o->gch.tt);
+ setnilvalue(o);
+ }
(NOW can be a global variable that you set before the suspicious call to
lua_gc.) Then we can see what the collector is marking, what it is
erasing...
