Bypassed definition prevents an undefined error #57315
Description
Code:
global flag=false
function fun()
global flag
print(1)
if flag
flag_2=true
else
print(2)
if flag_2
print(3)
end
print(4)
end
print(5)
return true
end
fun()and I got
125true
Expected (as I replace the global flag with false):
global flag=false
function fun()
global flag
print(1)
if false
flag_2=true
else
print(2)
if flag_2
print(3)
end
print(4)
end
print(5)
return true
end
fun()and got
12ERROR: UndefVarError:
flag_2not defined
Stacktrace:
[1] fun()

@ REPL[3]:1
When definition of flag_2 is bypassed by the global flag, the code failed to raise an error and shouldn't continue running (as the number 5 printed)
