--- Comment #1 from mhh <maxhaton@gmail.com> ---
2.072.2 to 2.094.2: Failure with output:
-----
/usr/lib/gcc/x86_64-linux-gnu/5/../../../x86_64-linux-gnu/crt1.o: In function
`_start':
(.text+0x20): undefined reference to `main'
collect2: error: ld returned 1 exit status
Error: linker exited with status 1
-----

Since      2.095.1: Segfault and no output


This is a regression.

This forms a cycle in the overload list of `foo` (so overload apply becomes an
infinite loop).

To complete the circle, the test case should be:

---
void foo(int){};
alias bar=foo;
void bar(bool){}
alias foobar=bar;
alias foo=foobar;
void foobar(float){}
---

As this constructs a tree where no single node representation is directly connected to any of its cyclic references.
