The referenced issue is at https://github.com/dosemu2/fdpp/issues/212
The patch was applied using unix2dos on the patch file
then `patch -p1 --binary` with the patch file as stdin.
The original used a new define for the maximum path length.
As there is no difference to our current SFTMAX define I
changed this hunk to retain the SFTMAX use.
This fixes a bug when eg function 3Dh receives a buffer
that starts with ".\" but the byte in memory before this
buffer happens to be also a dot. I ran into this problem
semi-randomly during building EDR-DOS with the most recent
WarpLink build. If WarpLink was placed somewhat low in the
Low Memory Area then one of its function 3Dh calls would
happen to have a dot before the pathname buffer. (I had to
load lCDebug using the last fit strategy then enter TSR mode,
to catch the bug without the presence of the debugger working
around the occurrence of the bug.)

Subject: [PATCH] truename: fix array overrun [fixes #212]
src[-2] was peeking into a random memory location.
It seems entire truename() is written by some morons... :(
Its completely unreadable and full of bugs.
fd kernel
FreeDOS kernel - current 0xFD version is 2.43 (2043)
The FreeDOS kernel implements the core MS/PC-DOS (R) compatible functions. It is derived from Pat Villani's DOS-C kernel and released under the GPL v2. Please see http://www.freedos.org/ for more details about the FreeDOS (TM) Project. This was originally a branch based on 2042 SVN 0xFD kernel; the full svn history has since been added to git (see other branches) and current development of release kernels are available here. Please fork and submit a Pull Request!
Compiled kernels ready to use (just copy kernel.sys over an existing install) are available at http://www.fdos.org/kernel/testing/git/ - also available are the source archive and fdpkg compatible packages. *** TODO update links/upload archives
This version of the kernel is intended only for 8086+ or 80386+ IBM compatible computers in continuation of the goals of the FreeDOS Project. Please see http://www.fdos.org/kernel for my 0xDC kernel that is work on merging back in some of the original portability aspects and other supported features at the cost of some compatibility with older hardware/software.

Now with automatic builds and soon tests
