[Bug lto/44966] weak aliases LTO with gold causes ICE in lto_symtab_merge_decls_1

["andi-gcc at firstfloor dot org" <gcc-bugzilla at gcc dot gnu dot org>]

------- Comment #9 from andi-gcc at firstfloor dot org  2010-07-20 10:15 -------
I ignored all nodes with NULL node/vnode now as 
you suggested and get much further.

It takes a lot of memory in multiple lto1 runs (>2GB in some cases)

Then after a long time I have a new ICE in the garbage collector

Any ideas how to debug this?

600       while (table->high_bits != high_bits)
(gdb) p table
$1 = (struct page_table_chain *) 0x0

Apparently there's a non GC object in the garbage collector?
