As discussed in https://github.com/ivmai/bdwgc/issues/13, this was fixed in
boehm-gc but due to the stage 4, I don't expect to the boehm-gc version be
upgraded. Does a workaround should be proposed?
You can try that but 1) this is untested (and probably is not enough), 2)
NO_PTHREAD_GET_STACKADDR_NP macro does not exists in current boehm-gc so
probably it will create problems too.
