5.1alpha count and line hook

[Jan Kratochvíl <jan.kratochvil@...>]

Hello,
i experienced strange behaviour with lua 5.1 alpha using count hooks 
and line hooks together. Sometimes i didn't get the line
hook so i traced it inside lua and i found that in traceexec is this
<quote:line 65>
 if (mask > LUA_MASKLINE) {  /* instruction-hook set? */
   if (L->hookcount == 0) {
     resethookcount(L);
     luaD_callhook(L, LUA_HOOKCOUNT, -1);
     return;
   }
 }
 if (mask & LUA_MASKLINE) {
</quote>
As you can see i got count hook but i can't got line hook because of 
return on line 69.
Removing this return fixed my problem. But is it safe to do? (i don't 
understand lua internals so
i don't know if luaD_callhook can be called twice in traceexec, so i am 
rather asking :) )

Thanks
