Hello,
First, I am maintaining the tango and pytango package in the Debian distribution.
So during the gcc5 rebuilt I got affected by something strange, first in the tango library[1].
Then a problem with pytango[2] which depends on tango. you will find a interesting comment in [3].
And a small test program whcih shows the problem in [4].
So I would like your opinion about this pytango FTBFS.
It seem that gcc5.2 generate different symbols in tango (abi-cxx11) than in pytango (no abi-cxx11).
I do not understand why, so I am wondering if this is a bug in pytango, tango or in gcc.
thanks for your help
Frédéric
