With gdb HEAD (technically users/simark/update-gnulib @

I've seen a similar error on more esoteric platforms. I believe it is a
toolchain bug somewhere relating to extern thread_local variables. However, it
may make sense to rework this code not to require extern variables (using
getters/setters or somesuch).
