Comment 1 Rafal Luzynski 2017-12-02 19:51:29 UTC 
See also: bug 1423303.
Comment 2 Nicolas Sapa 2017-12-30 03:07:49 UTC 
Still present in Fedora 27.
Comment 3 Jonathan Wakely 2018-02-07 13:52:16 UTC 
"Requires: libstdc++ < 7.0.0" seems to be an attempt to ensure that an
ABI-compatible version of libstdc++ is used, and conservatively names
a version that is known to be compatible (rather than assuming that
all future versions will be compatible).

The libstdc++ from GCC 8.x is ABI compatible wiuth 3.4.x, so bumping 
the Requires: to 9.0.0 (allowing any GCC 8.x release) is fine.
Comment 4 Stéphane PIQUEMAL 2018-02-23 09:28:58 UTC 
I just fall into this issue with Fedora 26.
I already have compat-gcc-34-c++-3.4.6-41.fc26.x86_64 installed.
But it's now blocking any "dnf updates" because of the libstdc++ dependancy.
What are the current action to solve this problem ?
Are we waiting for an update on this package, or did I miss a workaround ?

> Are we waiting for an update on this package, or did I miss a workaround ?

Updated packages are needed, but the maintainer has been very busy with gcc-8.0.1 in rawhide, and compat-gcc-34 is much lower priority.

The updates have been submitted now and will be in updates-testing soon.
