From 88a1f520d2d54d362dc2f29a0fad2cf0029c8918 Mon Sep 17 00:00:00 2001 From: Christopher Ferris Date: Thu, 7 Aug 2014 16:21:21 -0700 Subject: Add a way to disable backtracing in malloc debug. The property libc.debug.malloc.nobacktrace set to non-zero disables getting backtracing when using mode 1 or mode 10.
