gcc6 @6.1.0: functional:1726:40: internal compiler error: in assign_temp, at function.c:961

[noloader (Jeffrey Walton)]

I'm working on OS X 10.8.5. The machine has MacPorts 2.3.4 installed.

I'm attempting to compile ​Jack Lloyd's Botan with GCC 6.1. Botan is a C++ TLS library.

You could try the gcc7 port instead. If the problem persists with that version of gcc, you could report it to the developers of gcc.

GCC-7 fails to install (error message below).

The issue was reported to the GCC devs at ​http://gcc.gnu.org/bugzilla/show_bug.cgi?id=71812.

$ sudo port install gcc7
--->  Computing dependencies for gcc7
Error: Unable to execute port: Can't install libgcc-devel because conflicting ports are active: libgcc

[noloader (Jeffrey Walton)]

Jakub Jelinek offered ​http://gcc.gnu.org/bugzilla/show_bug.cgi?id=71210 as a potential dup. It looks like the GCC folks fixed it some time ago.

Thanks to Jelinek for pointing it out.

$ sudo port install gcc7

Then sudo port -f deactivate libgcc first.

Thanks, I'll update the gcc6 port to 6.2.0 soon.
