https://crrev.com/c/3399252 fixed a heap overrun in iOS intermediate dump processing. This is a follow-up to that change to harden `CrashHandler` against similar crashes: 1) Ensure the destructor of `ScopedAlternateWriter` is invoked to restore `InProcessHandler::writer_` state before processing the intermediate dump (otherwise, a signal raised by the intermediate dump handler would dereference the empty `std::unique_ptr` in `InProcessHandler::writer_`). 2) Harden `InProcessHandler` to check if `writer_` is empty before handling signals or exceptions Change-Id: I1e63a496395b26681632302e8915b4433897037a Bug: 391 Reviewed-on: https://chromium-review.googlesource.com/c/crashpad/crashpad/+/3401766 Reviewed-by: Justin Cohen <justincohen@chromium.org> Reviewed-by: Mark Mentovai <mark@chromium.org> Commit-Queue: Mark Mentovai <mark@chromium.org>
