            Bug ID: 50293
           Summary: Backport 6c99e631201a to 12.0.1 to fix SCEV issue
                    causing a mis-compile
           Product: libraries
           Version: trunk
          Hardware: PC
                OS: All
            Status: NEW
          Severity: enhancement
          Priority: P

It would be great if we could pick d65e5f60f110 (adds tests) and 6c99e631201a
(fix) onto the 12.0.1 branch.

It fixes a mis-compile as illustrated in the changed test, which users can hit
with relatively simple C code.
