It is likely a duplicate of PR58067 which was fixed for gcc 4.9.

TLS ABI only covers the small model.  There is no demand to

extend TLS ABI to support medium/large models.

(In reply to comment #3)

 Confirmed based on the dups.



This is ABI limitaton, we can't use indirect call that is necessary to reach

__tls_get_addr in the large memory space here. IIRC, -mtls-dialect=gnu2 should

be used with -mcmodel=large to solve this problem, but the former option is

somehow untested.



We shouldn't ice here, though.



I am adding HJ for his opinion on ABI issue.
