Description __vic 2012-06-15 08:21:16 UTC 
The same problem as fixed in Bug 12595 but in Release 4.7: versioned symbols in the static libstdc++.a
Comment 1 Richard Biener 2012-06-15 08:27:53 UTC 
Please provide more information, your assessment it's the "same" bug might not
be true.
Comment 2 __vic 2012-06-15 08:30:06 UTC 
$ uname -a
Linux m246 2.6.18-194.26.1.el5 #1 SMP Tue Nov 9 12:54:40 EST 2010 i686 i686 i386 GNU/Linux
$ cat /etc/*-release
CentOS release 5.4 (Final)

When building on

$ uname -a
Linux jansmb 2.6.9-103.ELsmp #1 SMP Fri Dec 9 04:31:51 EST 2011 i686 i686 i386 GNU/Linux
$ cat /etc/*-release
CentOS release 4.9 (Final)

it's all right
Comment 3 __vic 2012-06-15 08:34:13 UTC 
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?
Comment 4 __vic 2012-06-15 08:57:21 UTC 
Note: undocumented configure option --disable-symvers helps but I think building with default parameters must work properly
Comment 5 __vic 2012-06-15 10:22:36 UTC 
The exact description:

/usr/bin/ld: failed to set dynamic section sizes: Bad value
collect2: error: ld returned 1 exit status


$ nm lib/libstdc++.a | grep adopt

It's not undocumented

isn't this PR 52689 ?

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

Probably it is.
Comment 10 __vic 2012-06-15 10:36:24 UTC 
When 4.7.1 will be released?
Comment 11 Jonathan Wakely 2012-06-15 10:37:41 UTC 
yesterday

http://gcc.gnu.org/gcc-4.7/

marking as dup, please reopen if 4.7.1 doesn't fix it
