--- Comment #14 from Ian Lance Taylor <ian at airs dot com> 2011-02-14 21:32:08 UTC --- I built current binutils mainline on a Fedora 14 x86_64 system using --enable-gold. I built current gcc mainline on the same system using --with-ld to point it at the newly built gold linker. I compiled and ran the test case, and it worked fine. There must be some difference between your system, but I don't know what it is. Can you attach the a.out, the libc.so that it uses, and the core dump? Perhaps I will be able to see something.
