commit 4028eefe6190551c8be96cd451337dea2808742b
Author: Jean-Marc Lasgouttes <lasgout...@lyx.org>
Date: Mon Feb 25 17:37:06 2019 +0100
Make callstack printing useful and optional
When callback printing is enabled, link lyx with -rdynamic, so that
stacks have LyX symbols available.
Add option --disable-callstack-printing to configure.
Running "size" on binary:
* with callstack printing support
text data bss dec hex filename

* without callstack printing support
text data bss dec hex filename
