    _______________________________________________________

Details:

Crash can be reproduced by loading script text_effects.lua and doing on core
buffer:


/repeat 10000 /debug


Apparently no problem with standard lua (only with luajit).

Fix: call lua_pop() for values returned by lua functions.

Problem reported on #weechat by xt.
