** Description changed:
+ [Impact]
+
+ * with gcc-5 default, and llvm-3.4 built with the gcc-4.9, people can't
+ link programs using cxx11 support
+
+ [Test Case]
+
+ * compile a program using cxx11 e.g. using boost libraries
+
+ [Regression Potential]
+
+ * llvm-3.4 is a compiler, and the
backported + uploaded the mentioned commit - this bug probably needs SRU
information per comment #26 before it'll be accepted though.
thanks!

The package needs to be build with gcc5.2 to have the correct (dualabi)
symbols in the library.
Therefore the back port to 15.10 is definitely needed! Otherwise 3th
parity libs cannot link against the clang compiler (what we definitely
need)
In generall all librarys on a dualabi system

Unsure what to do about 15.10, the current package is built with gcc 4.9
and I'm unsure what's the impact of building with gcc5 and if that's

Could you also maybe explain what you changed in the regexp and why and
how that resolves the issue?

The rexexp checks for availible compiler versions.
Theregexp checks for X.X.X i changed the regexpt to X.X
The fallback was to use gcc 4.9 which was availible on ubuntu.
The new gcc is 5.2, therefore now the new regexpt matches.
I do not checked the originial debian rules from the debian

I have no clue howto tell the buildserver to wait longer for the result for the

other bugreport

Thanks, Matthias. Your PPA still hasn't compiled the package. Once its
done I will try it and let you know. I'm fairly confident it will work
just fine.
