2019-08-17runtime: scan write barrier buffer conservativelyIan Lance Taylor1-1/+8
In gccgo, we insert the write barriers in the frontend, and so we cannot completely prevent write barriers on stack writes. So it is possible for a bad pointer appearing in the write barrier buffer. When flushing the write barrier, treat it the same as sacnning the stack. In particular, don't mark a pointer if it does not point to an allocated object. We already have similar logic in greyobject. With this, hopefully, we can prevent an unallocated object from being marked completely. Reviewed-on: https://go-review.googlesource.com/c/gofrontend/+/190599 From-SVN: r274598
