            Bug ID: 18076
           Summary: mips: segfault in _bfd_elf_gc_mark_rsec
           Product: binutils
           Version: 2.25
            Status: NEW
          Severity: normal
          Priority: P2

lj_vm.s

In Debian, compiling trafficserver 5.2.0 causes ld to segfault in
_bfd_elf_gc_mark_rsec.

Debian log:
https://buildd.debian.org/status/fetch.php?pkg=trafficserver&arch=mipsel&ver=5.2.0-3&stamp=1425296797
 

I managed to reduce this down to one assembly file (attached) which causes ld
to segfault in the same place when run like this:
> as -o lj_vm.o lj_vm.s
> ld -L/usr/lib/mipsel-linux-gnu -v lj_vm.o -lc

(Replace the -L directory with wherever libc.so is located)

Affects at least 2.25 and latest HEAD.
