Can I install gcc-8 from rawhide on F27?

[Neal Becker]

There's a bug in gcc-7.3.1 that causes a crash on some code I need.  Is it 
safe to install gcc-8 from rawhide on F27?

That would be a question for the Fedora Test list.

Is there a patch for the bug?   You may be better off waiting for an updated
gcc-7 as gcc-8 probably has new bugs.

You can try installing the gcc package from rawhide (or probably better 
the F28 repository, currently at beta), but the usual problem with doing 
this sort of thing is that you find you have to update a lot of dependent 
packages as well, and it ends up simpler and probably safer just to update 
the whole system to the later version.

In the case of gcc you might be okay to do it, as I don't think there are 
many dependent packages and they look fairly self-contained but it may 
depend on what else is installed.

There are also alternatives you could try, for example if it is a package 
you could use mock to try building it under F28, or you could build your 
software an F28 docker container.
