test program (C, 50 lines, 2 KiB, derived from coreutils cksum)
Hello, attached test program behaves unexpectedly when compiled with -O1 or
higher and for aarch64_be. The value of the variable `data` apparently changes
when it shouldn't.
The issue has been observed with GCC 15.2.0. I did not test newer/older GCC
versions.
