Ideally I need whatever is required to recreate the problem with just gold and
absolutely nothing else. If I have to get into building clang, experience
tells me that I will almost certainly not be able to recreate the problem.
That said, I actually looked at the backtrace, and I see this:
#3 0x0000000000571ee1 in gold::Symbol_table::add_from_pluginobj<64, false>
(this=0x7fffffff7f60, obj=0x3afaef90, name=0x0, ver=0x0,
sym=0x7fffffff7940) at
/var/tmp/portage/sys-devel/binutils-9999/work/binutils/gold/symtab.cc:1340
#4 0x0000000000534f80 in gold::Sized_pluginobj<64, false>::do_add_symbols
(this=0x3afaef90, symtab=0x7fffffff7f60, layout=0x7fffffff81c0)
at
/var/tmp/portage/sys-devel/binutils-9999/work/binutils/gold/plugin.cc:1074
The fact that name == NULL in the call to add_from_pluginobj very strongly
suggests that this is a bug in the plugin. The plugin is trying to add a
symbol with a NULL name. That makes no sense and is leading directly to the
crash.
