Stack from ghstack (oldest at bottom):

We can now get cpp stack trace by calling torch.utils.get_cpp_backtrace()

Sample output when calling from a torch_dispatch stack:

get_backtrace can get called a lot, so you are going to want to static this so that this subprocess call only happens once. It may also be a good idea to not test this by default, and gate by an envvar, to avoid unexpected surprises

We can now get cpp stack trace by calling torch.util.get_cpp_backtrace()

Sample output when calling from a torch_dispatch stack:

Hey @SherlockNoMad.
You've committed this PR, but it does not have both a 'release notes: ...' and 'topics: ...' label. Please add one of each to the PR. The 'release notes: ...' label should represent the part of PyTorch that this PR changes (fx, autograd, distributed, etc) and the 'topics: ...' label should represent the kind of PR it is (not user facing, new feature, bug fix, perf improvement, etc). The list of valid labels can be found here for the 'release notes: ...' and here for the 'topics: ...'.
For changes that are 'topic: not user facing' there is no need for a release notes label.

We can now get cpp stack trace by calling torch.utils.get_cpp_backtrace()

Sample output when calling from a torch_dispatch stack:
