  Hash : 2edec864
  Message : Improve stack backtraces on Linux. This switches the Linux crash handler to use addr2line when it is available. Addr2line is much better at converting addresses into readable information. The downside is that we must use a system call to a binary since it's not easy to integrate with addr2line source. Bug: angleproject:5239 Change-Id: I13cbaa4ba30166718fb12d924c76ba4f2675453c Reviewed-on: https://chromium-review.googlesource.com/c/angle/angle/+/2515265 Reviewed-by: Shahbaz Youssefi <syoussefi@chromium.org> Reviewed-by: Jamie Madill <jmadill@chromium.org> Commit-Queue: Tim Van Patten <timvp@google.com>
