Right now if formatting a ScopedDebugInfo hits a segfault, we won't output any information about the prior ScopedDebugInfos on the stack. (Note that SERVER-98667 takes care of the case where we hit a tassert/uassert.)

One approach would be to implement some sort of ScopedDebugInfoStack iterator that would replace the current callers of ScopedDebugInfoStack::getAll. However, the current approach that prevents re-entrancy would have to be modified, and the callers of ScopedDebugInfoStack::getAll would likely have to deal with more complexity.
