Bug Description
---Problem Description---
Please pick up r239762 from the FSF gcc-5-branch as a bug fix for upstream bug PR72863. In the best case, the unfixed compiler will produce inefficient code, but it can also cause incorrect code to be generated at high optimization levels. The testcase in the upstream bugzilla can be used to verify the fix.
---Steps to Reproduce---
See testcase in https:/
SRU acceptance criteria: The new test case passes, and the build doesn't show regressions.
