Please provide more information, your assessment it's the "same" bug might not
be true.

$ uname -a

When building on

$ uname -a

GNU/Linux
$ cat /etc/*-release
CentOS release 4.9 (Final)

it's all right

When I'm trying link libstdc++.a statically to my .so I see messages like:
"undefined versioned symbol name std::defer_lock@@GLIBCPP_3...."

$ nm libstdc++.a | grep @

shows me that archive contains versioned symbols. Do you need the entire list?

Note: undocumented configure option --disable-symvers helps but I think
building with default parameters must work properly

It's not undocumented

Ok. But still. It must not be a mandatory option to build correct static lib
