clang 11.0.0-rc2 also can't find problems in the two above code fragments.
This code problem doesn't occur in gcc source code, but there are about
a dozen cases in the linux kernel.

Fixed for pointer/allocatable arrays.
Still to be done: scalar pointers/allocatable; here, one needs to be careful as
pointer/always pointer is already used for, e.g., struct mapping – and always

Hello,
Any news on the subject?
Would you advise in the meantime to discard the LTO (with the -fno-lto option)

I think the problem is that check_no_overlap only looks at later m_store_info
stores that would overlap and cause problems.
But in this case, the problem is that we'd need to check earlier m_store_info
