Do you know how to use "git bisect"? If so, could you maybe try to
bisect which commit between v2.12.0 and v3.0.0 introduced this problem?

  address_space_stw_le_cached: Assertion `addr < cache->len && 2 <=

Status in QEMU:
  New

Bug description:
  When running OpenBSD-current as a guest, the following assertion is
  hit after a few seconds, resulting in the virtual machine to crash:

  ```
  qemu-system-x86_64: /build/qemu/src/qemu-3.0.0/include/exec/memory_ldst_cached.inc.h:85: address_space_stw_le_cached: Assertion `addr < cache->len && 2 <= cache->len - addr' failed.
  ```

  Host is Arch Linux stable, running on x86_64.

  Qemu version is 3.0.0, installed via the standard Arch Linux package.

  Version 2.12.1 didn't exhibit this behavior.

I suspect this is a known bug, fixed in master in commit db812c4073c77.
You could test that by cherry-picking it to 3.0 or just testing against
master.

In the absence of further information from the submitter, it seems
reasonable to assume that this is indeed the bug fixed by commit
db812c4073c77 (which resulted in this assertion when running OpenBSD
guests). That commit is in 3.1, which was released in December.


** Changed in: qemu
