Hallo together,

with the actual gcc 11 master branch i got the following build error:=20

/usr/bin/ld: libCMakeLib.a(cmWorkerPool.cxx.o): in function
`std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<ch=
ar>
>::shrink_to_fit()':
/usr/include/c++/11/bits/basic_string.h:953: undefined reference to
`std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<ch=

53:
more undefined references to `std::__cxx11::basic_string<char,
std::char_traits<char>, std::allocator<char> >::reserve()' follow

I think anything is wrong with the basic_string.h:953 header file the header
file from gcc 10 works.=20

best regards
