--- Comment #20 from Cary Coutant <ccoutant at gmail dot com> ---
The library libopendbx.so has an allocated common symbol:
24: 0000000000203090 1 COMMON GLOBAL DEFAULT 23 __gnu_lto_v1
(This is a marker symbol emitted by GCC during LTO.)
Gold is doing two things wrong here:
(1) It's processing the symbol from the shared library as a normal common
symbol, and trying to allocate a 1-byte common block with alignment of
0x203090. Instead, we should simply treat the symbol as a regular defined
symbol.
(2) In mistakenly taking the symbol's address as a requested alignment, we end
up with some weird address layout because the alignment is not a multiple of
the page size. That results in the unusually large alignment of the .bss
section, and also results in the internal error in set_offset reported in the
more recent comments.
