Here is what I know so far:
- If built with -O2 -fstack-protector-strong, one test fails on ppc64le.
- If built with -O2 -fstack-protector, that test passes.
- If built with -O2 -fstack-protector -fno-strict-aliasing, that test passes.
- The -Wstrict-aliasing flag, in combination with any of the above, issues no warnings.
Whether there is actually illegal aliasing going on or not is still unknown. The investigation continues...
This may be a duplicate of bug 1555151. As in that bug, the test fails because of an uninitialized value. Also, building with -O2 -fstack-protector-strong -fno-tree-sra succeeds. It is a different test case from that bug, and a different architecture, and didn't show up until gcc 9, but the fact that -fno-tree-sra fixes the test is suspicious.
