Sorry, my description wasn't accurate.


The real problem is that clang-built executables link with the older 
version of libgcc_s.so (/lib/libgcc_s.so.1), and the current gcc 
supplies its own version, ex. /usr/local/lib/gcc48/libgcc_s.so These two 
libgcc_s.so are in conflict. The reason why FreeBSD base system has an 
older version has to do with the changed gcc license, which became 
incompatible. The reason clang-built executables link with 
/lib/libgcc_s.so.1 is that an "unwind" API is only implemented there.


I guess the real question is: what is the best replacement of an unwind 
API? Does clang/llvm supply it? Or what is the best solution of this 
problem?


This problem has been in FreeBSD for a long while, with no solution in 
sight. It is related to clang, so I decided to ask here for an opinion.


Thank you,
