--- Comment #1 from Ian Lance Taylor <ian at airs dot com> --- Normally libgo.so will get the symbol _Unwind_GetLanguageSpecificData from libgcc_s.so. The first step here is to find out why that didn't happen. Was libgo.so not linked against libgcc_s.so? Does libgcc_s.so not define _Unwind_GetLanguageSpecificData?
