Re: Curious... on readline history patch -- round up memory allocs?

The change was in reference to this bug report:
http://lists.gnu.org/archive/html/bug-bash/2016-09/msg00107.html

The problem was that bash tried to allocate memory from the start
based on the value of HISTSIZE, but this proved problematic for users
which used a large HISTSIZE to have unlimited history.

The commit is here
http://git.savannah.gnu.org/cgit/bash.git/commit/?h=devel&id=61c476d20d32dfd389c79fd4f2161a780685e42e

And the entry in the changelog:

+lib/readine/history.c
+ - add_history: if allocating the history list for the first time,
+ make sure the max history list size isn't so large that it will
+ cause allocation errors. Cap it at MAX_HISTORY_INITIAL_SIZE
+ (8192). Reported by Sean Zha <address@hidden>
