READLINE PATCH REPORT
=====================
Readline-Release: 7.0
Patch-ID: readline70-001
Bug-Reported-by: Sean Zha <[email protected]>
Bug-Reference-ID:
<bn3pr01mb13657d9303eb94bf6e54216e8c...@bn3pr01mb1365.prod.exchangelabs.com>
Bug-Reference-URL:

Bug-Description:
Readline-7.0 changed the way the history list is initially allocated to reduce
the number of reallocations and copies. Users who set the readline
history-size variable to a very large number to essentially unlimit the size
of the history list will get memory allocation errors
Patch (apply with `patch -p0'):
