On Windows (and probably elsewhere) it's possible that something else on the system changes the memory map between when a memory snapshot range is added to the minidump, and when the process's memory is actually read from the target and written to the .dmp file. As a result, failing the Read() should not result in aborting the minidump's write, which it previously would have. Bug: crashpad:234 Change-Id: Ib24e255a34fa2e1758621d3955ebc7a0f96166e2 Reviewed-on: https://chromium-review.googlesource.com/1096452 Reviewed-by: Joshua Peraza <jperaza@chromium.org> Commit-Queue: Scott Graham <scottmg@chromium.org>
