[EGIT] [core/efl] master 04/07: eo_debug: Also print out the current backtrace

[Jean-Philippe ANDRÉ]

jpeg pushed a commit to branch master.

http://git.enlightenment.org/core/efl.git/commit/?id=3dc140abfb30b94eae3093fd565f2f111c03be04

commit 3dc140abfb30b94eae3093fd565f2f111c03be04
Author: Jean-Philippe Andre <jp.an...@samsung.com>
Date:   Thu Sep 28 10:25:18 2017 +0900

    eo_debug: Also print out the current backtrace
    
    We can't use EINA_LOG_BACKTRACE=1 for that as eo_lifecycle itself prints
    out ERR messages for its backtrace dump.
