The assertion that failed:

    assert(s->_all_mallocs.size() == total_size) failed: Total != sum of parts

was added by the following fix:

    JDK-8298992 runtime/NMT/SummarySanityCheck.java failed with "Total committed (MMMMMM) did not match the summarized committed (NNNNNN)"

and that fix is included in jdk-22+13-950-tier3 so I'm
labeling this bug as a regression.
