There is a gdb-local patch to deal with interrupts during completion. The original thread adding this patch is here: https://sourceware.org/ml/gdb-patches/2011-06/msg00147.html I believe readline now implements the approach suggested by Chet Ramey: https://sourceware.org/ml/gdb-patches/2011-06/msg00493.html So, I believe this patch can be removed. readline/ChangeLog.gdb 2018-10-07 Tom Tromey <tom@tromey.com> * Makefile.in (xfree.o): Don't depend on readline.h. * xfree.c (xfree): Remove gdb workaround. * xmalloc.h (xfree): Remove #define.
