            Bug ID: 245369
           Summary: <jemalloc>: jemalloc_arena.c:647: Failed assertion:
                    "nstime_compare(&decay->epoch, &time) <= 0"
           Product: Base System
           Version: CURRENT
          Hardware: amd64
                OS: Any
            Status: New
          Severity: Affects Only Me
          Priority: ---
         Component: bin
          Assignee: bugs at FreeBSD.org
          Reporter: stevenhaocheng at 163.com

Here's the issue: 
<jemalloc>: jemalloc_arena.c:647: Failed assertion:
"nstime_compare(&decay->epoch, &time) <= 0"
Abort (core dumped)

I got this output many many times, and I'm really upset when I see this because
it usually appears when my git clone almost ends/download almost finishes/cmake
configuration almost finishes. This time, I got it when I was comfiguring llvm
using cmake. I had to do that work again! And it costs time! This message will
just randomly pop onto my screen when I am operating my disk ("quickly and
vastly", i.e. git allocating space for ENORMOUS downloads like llvm-project, or
unzip extracting a zip file that is several GiB big), regardless of the command
I invoked. 

Notes:
Output of uname -a:
