--- Comment #10 from gcc-bugs at marehr dot dialup.fu-berlin.de ---
Hi,
I did built gcc from git sources
[https://github.com/gcc-mirror/gcc/commit/156d24841, gcc version 8.0.0 20171215
(experimental) (GCC)] today and ran into the same? error.
I could extract this minimal code snippet from our code base that does not work
with g++-8, but with gcc version 7.2.1 20171128 (GCC).
```
class a {};
class b {};
class c : b, a {
__attribute__((always_inline)) c operator=(c);
};
```
~~~~~~~
Error log:
internal compiler error: Segmentation fault
__attribute__((always_inline)) c operator=(c);
