[llvm-dev] lld/x86_64 linux elf invalid link_map

I'm having a curious issue with LLD/x86_64 linux/elf (Ubuntu 14.04); 
Where the l_addr of the link_map is invalid when linked with lld, but is 
fine with gnu ld.

I'm using the libgc (boehm) code which when initializing reads the 
DYNAMIC/DEBUG link_map data, and crashes because the l_addr field has 
value out of readable memory. The strange this is that it happens only 
on some linux systems even though they're the same ubuntu version.

My question is, what could possibly cause this, where can I start looking?
