dump_thread32() in aout_core_dump() does not clear the user32 structure allocated on the stack as the first thing on function entry. As a result, the dump.u_comm, dump.u_ar0 and dump.signal which get assigned before the clearing, get overwritten. Rename that function to fill_dump() to make it clear what it does and call it first thing. This was caught while staring at a patch by Derek Robson <robsonde@gmail.com>.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
