I'm trying to run the attached program in Lua 5.2.2 and 5.4.3 but I'm getting different number of arguments in Lua stack when I check in hook function. Is anything changed related to Lua hook function call?.
I compiled the attached program as:
In 5.4:
cc -o test_set_hook test_set_hook.c -Wall -I /var/views/lua/lua-5.4.3/src/ -L/var/views/lua/lua-5.4.3/src/ -lm -llua
In 5.2:
cc -o test_set_hook test_set_hook.c -Wall -I /var/views/lua/lua-5.2.2/src/ -L/var/views/lua/lua-5.2.2/src/ -lm -llua
I'm doing this compilation in FeeBSD -11.4 (AMD 64).
Here is the output of the program:
In Lua 5.4:
