works for me, can anybody else reproduce this?
On a different machine, also mostly testing/unstable
with libstdc++6 from experimental:
$ cat test.cpp
#include <cstdio>
int main() {
puts("Hello World!\n");
return 0;
}
$ g++ -o test test.cpp
$ ./test
./test: symbol lookup error: /usr/lib/libstdc++.so.6: undefined symbol: _ZNSt7num_getIcSt19istreambuf_iteratorIcSt11char_traitsIcEEE2idE, version GLIBCXX_3.4
$
Additionally, with v4.5.0-5
$ readelf -aW /usr/lib/libstdc++.so.6 | fgrep
_ZNSt7num_getIcSt19istreambuf_iteratorIcSt11char_traitsIcEEE2idE@@GLIBCXX_3.4
144: 000e9734 4 OBJECT UNIQUE DEFAULT 28
_ZNSt7num_getIcSt19istreambuf_iteratorIcSt11char_traitsIcEEE2idE@@GLIBCXX_3.4
$
but with v4.4.4-1
$ readelf -aW /usr/lib/libstdc++.so.6 | fgrep
_ZNSt7num_getIcSt19istreambuf_iteratorIcSt11char_traitsIcEEE2idE@@GLIBCXX_3.4
144: 000ef6b4 4 OBJECT WEAK DEFAULT 28
_ZNSt7num_getIcSt19istreambuf_iteratorIcSt11char_traitsIcEEE2idE@@GLIBCXX_3.4
$
I don't know whether the WEAK/UNIQUE difference is significant, I just happened
to notice it.
