Compilation never ends

[michaelsilva]

I'm a c# developer and i'm trying develop a finite state automata in c++ but the member function chaining is causing compilation never ends.
The project can be found in my GitHub https://github.com/michael-silva/fsa-cpp in the test.cpp file if i reduce the number of member functions chaining the compilation runs, however more calls cause compilation never ends.

Hi,

Welcome to cplusplus :+)

Unfortunately, your linked 404'd.

Not that I know anything about your problem, I just mention this so you may get help from others :+)

Good Luck !!

The link got the `,' symbol


I can compile test.cpp with gcc 5.3 and clang 3.7 in less than 2 seconds.

¿do I need to do something in order to reproduce your issue?
I'd rather not.

I'm using gcc 5.3 and when I try compiling with command below never ends
g++ -static-libstdc++ -std=c++14 "test.cpp" -o "test" .

If i compile this code works.

auto state2 = FiniteStateAutomata::Deterministic<char>()
		.Alphabet('0', '1', '-', '.')
		.On('1').SetValues("123456789")
		.States()
		.When('0').To(DOT)
		.When('1').To(DOT)
		.When('-').To(N1)
		.On(N1)
		.When('1').To(DOT)
		.On(DOT).Accept()
		.When('.').To(N2);

But if i add more calls the compilation don't finish.

auto state2 = FiniteStateAutomata::Deterministic<char>()
		.Alphabet('0', '1', '-', '.')
		.On('1').SetValues("123456789")
		.States()
		.When('0').To(DOT)
		.When('1').To(DOT)
		.When('-').To(N1)
		.On(N1)
		.When('1').To(DOT)
		.On(DOT).Accept()
		.When('.').To(N2)
		.On(N2)
		.When('0').To(N3)
		.When('1').To(N4)
		.On(N3).Accept()
		.When('0').Repeat()
		.When('1').To(N4)
		.On(N4).Accept()
		.When('1').Repeat()
		.When('0').Repeat();

It works with g++ -std=c++11
clang generates the same binary with 14 or 11 flag.

Report it as a bug.


By the way, you shouldn't add the binaries to git.
