I was testing some code on Coliru , and I got a strange output. I went down the code and could reproduce it with this simple piece of code :
int main()
{
π
}
The output on g++:
clang:
For instance, using just pi
(without the address-of) shows the expected result:
main.cpp:3:5: error: 'pi' was not declared in this scope
pi;
^
I tried to reproduce this on my machine, using g++ 4.9.2 and on others sites but I could not.
Is this some bug on this site, some config of these compilers ?
And why only using the address-of operator ( &
) shows this symbol ?
It's a bug on the site, as the compiler's output is not properly escaped. The compiler should output π
, but that's valid HTML, producing the pi symbol you see.
π
is html code for π. It looks like someone forgot to escape things properly.
