Abort (core dumped)

[Alejandro Sanchez <asanchez1987@gmail.com>]

A core dump occurred while trying to interactively apply (3-way) a
series of patches from a mailbox.

git version 2.20.1

Steps to reproduce:

alex@polaris:~/slurm/source$ git am -3 -i
~/Downloads/6033-18.08-final-patchset-v2.patch
Commit Body is:
--------------------------
Use correct signed/unsiged types.

Change a few variables in archiving to use the correct signed or
unsigned type to avoid implicit casting.

Bug 6033.
--------------------------
Apply? [y]es/[n]o/[e]dit/[v]iew patch/[a]ccept all: y
Applying: Use correct signed/unsiged types.
Commit Body is:
--------------------------
Remove unused static variable high_buffer_size.

It was set but never read.

Commit Body is:
--------------------------
Handle duplicate archive file names.

The time period of the archive file currently depends on submit or start
time and whether the purge period is in hours, days, or months.
Previously, if the archive file name already exists, we would overwrite
the old archive file with the assumption that these are duplicate
records being archived after an archive load. However, that could result
in lost records in a couple of ways:

 * If there were runaway jobs that were part of an old archive file's
 time period and are later fixed and then purged, the old file would
 be overwritten.
 * If jobs or steps are purged but there are still jobs or steps in
 that time period that are pending or running, the pending or running
 jobs and steps won't be purged. When they finish and are purged, the
 old file would be overwritten.

Instead of overwriting the old file, we append a number to the file name
to create a new file. This will also be important in an upcoming commit.
