OS X (configure --with-ns) typing unresponsive with Org and Viper

[Michael Brand]

Hi all

There is an issue described well in the bug report
https://debbugs.gnu.org/cgi/bugreport.cgi?bug=2409
that I would like to analyze. Due to lack of knowledge I would like to
ask for some help in this regard. What can I profile or debug with
gdb? What code is involved and which temporary changes could I try out
to track down the issue?

Michael
