relocation errors on solaris 10 u10 due to symbol versioning from ld

[Schneider, Bennett]

Hi,
After updating to solaris 10 u10, I've been seeing issues with libstdc++ that I believe are a result of output from the gnu linker (binutils 2.19).  I'm getting relocation errors when using certain symbols from libstdc++.  LD_DEBUG output shows that these are not being considered because the interpreter believes that they have the hidden bit set:
03888: 1: symbol=_ZNSi6ignoreEv;  lookup in file=a.out  [ ELF ]
03888: 1: symbol=_ZNSi6ignoreEv;  lookup in file=/home/server/lib/libstdc++.so.6  [ ELF ]
03888: 1: symbol=_ZNSi6ignoreEv;  hash index=3055;  version=32770;  skipping symbol with GNU version hidden bit set in file=/home/server/lib/libstdc++.so.6
03888: 1: symbol=_ZNSi6ignoreEv;  lookup in file=/lib/libm.so.2  [ ELF ]
03888: 1: symbol=_ZNSi6ignoreEv;  lookup in file=/home/server/lib/libgcc_s.so.1  [ ELF ]
03888: 1: symbol=_ZNSi6ignoreEv;  lookup in file=/lib/libc.so.1  [ ELF ]
03888: 1: 
03888: 1: 
03888: 1: libc.so.1: a.out: fatal: relocation error: file a.out: symbol _ZNSi6ignoreEv: referenced symbol not found

Using elfdump on libstdc++ shows that certain symbols seem to have extra bits set that are now being interpreted as hidden.  The previous output was for the ver to be 32770 (0x8002).  Gcc is being built with gas and gnu ld, and this seems to occur on both sparc and x86 distributions.  Building with sun ld does not show this problem.  It seems like these might be using the BSF_DYNAMIC flag, but I'm not familiar enough with the binutils source to confirm this.

Output from elfdump:

Has anyone seen similar behavior?  Alternately, can anyone provide a reason why some symbols are showing this version and if this behavior is correct?  I've searched both the bug listings and this mailing list, but haven't seen anything related.

Thanks,
