[Qemu-devel] [Bug 1795148] Re: address_space_stw_le_cached: Assertion `addr < cache->len && 2 <= cache ->len - addr' failed

[Peter Maydell]

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.
