   I found an ELF linker bug. What happened is if I defined a weak
   symbol plus a weak alias, the linker would dump core. Does anyone
   has a fix?

I checked in this patch, which should fix it.

(Your patch was incorrect, because weakdef is not a linked list,
except temporarily during elf_link_add_object_symbols).
