In PR 16979, a reference to malloc is being resolved to an unversioned reference in libmalloc.so. When linked with --as-needed, however, the dynamic table does not list libmalloc.so as a DT_NEEDED library. If we have a reference to an unversioned symbol in a shared object, and we later see a versioned definition in another shared object, we were overriding the first definition with the second in the process of defining the default version. As a result, we no longer think that the first shared object was actually needed to resolve any symbols, and we don't list it as a DT_NEEDED library. This patch fixes the problem by treating the two definitions as separate symbols, so the second definition does not override the first. 2016-03-30 Cary Coutant <ccout...@gmail.com> gold/ PR gold/16979 * symtab.cc (Symbol_table::define_default_version): Check for case where symbols are both in different shared objects. -- You are receiving this mail because: You are on the CC list for the bug. _______________________________________________ bug-binutils mailing list bug-binutils@gnu.org https://lists.gnu.org/mailman/listinfo/bug-binutils
