AddressSanitizer reveals real memory issues. Marking this pull request as draft until the underlying problem is solved.

I see a lot of failures: https://github.com/xiaoyeli/superlu/actions/runs/39046868270/job/117437223566
Are these real memory problems?
I usually run valgrind manually.

I asked Claude Code and got some fixes. Give a litte time to brush these up and get a proper merge request.

Are these real memory problems?

They are real, see #180. Some in the SuperLU library itself, other in the testing code or the examples. The two latter ones are also important, as users start with these and adopt it for their use cases.

Once this is done, I am looking for

1. adding UBSan (UndefinedBehaviorSanitizer), see [ci] Add UndefinedBehaviorSanitizer to AddressSanitizer job #184
2. removing SuperLU's memory debbung code, as it is inferior to external tooling like Sanitizers and Valgrind, see Remove code for memory debugging #181
3. making examples optional part of testing. Better coverage and we will detect regressions in examples.
