--- Comment #8 from Dominik Vogt <vogt at linux dot vnet.ibm.com> ---
All right, but what is the cause of that?  The commit that git-bisect found
seems to be completely unrelated(?)

Examples:
--
4 
_ZGTtNSt11range_errorC2EPKc 
transaction clone for std::range_error::range_error(char const*) 
version status: incompatible 
GLIBCXX_3.4.22 
type: function 
status: added 

5 
_ZGTtNSt12out_of_rangeD0Ev 
transaction clone for std::out_of_range::~out_of_range() 
version status: incompatible 
GLIBCXX_3.4.22 
type: function 
status: added
