Yup, the entry below confirms it:

Your vfs_write starts at 0xffffffff811b42b0, and "file" comes into scope
five bytes later.  This is the PR15123 scenario.  Does your environment
by any chance include $PR15123_DISABLE?  If so, unset that.  If not,
maybe it's time to debug dwflpp.cxx:translate_location, line 2411-ish.
