Ugh, annoying linker relaxation bug. The compiler correctly generates:
add %l7, %l3, %l3, %tgd_add(__gmpfr_flags)
[...]
call __tls_get_addr, %tgd_call(__gmpfr_flags)
mov %l3, %o0
ld [%o0], %g1
but the linker turns this into:
0x00014d14 <+504>: add %g7, %o0, %o0
0x00014d18 <+508>: mov %l3, %o0
0x00014d1c <+512>: ld [ %o0 ], %g1
so segfault on the load.
Filed as http://sourceware.org/bugzilla/show_bug.cgi?id=13301 for the linker.
Should we put a workaround in the compiler?
