Re: ios_base vanishing from shared objects

[Peter Schmid <schmid at snake dot iap dot physik dot tu-darmstadt dot de>]

I cannot reproduce your report. The libstdc++ libraries from gcc
version 3.1 20010315 contain, as far as I can tell, all ios_base
related symbols. Furthermore, I spot no additional ios_base symbols in
the shared or static library. I assume, that missing ios_base symbols
in the dynamic library are detected as additional failures when
running the testsuite; this is not the case for this version of gcc.

What symbols are missing in your copy of the dynamic library?

Maybe this is a binutils related problem? 

My System setup is:
SuSE 7.1
Glibc 2.2
Binutils:
GNU ld version 2.11.90.0.1 (with BFD 2.11.90.0.1)
Linux 2.4.2
target: i686-pc-linux-gnu
 
nm -C libstdc++.so.3.0.0
