Debug glibmm-CRITICAL

[Emil Nowak <emiml wp pl>]

Hello,
In my application from time to time I get "glibmm-CRITICAL" errors. They are
displayed on console. 
I wonder how can I debug them. 
So far I found that in glib there is env variable "G_DEBUG=fatal-criticals"
for that in Glib, but seems it doesn't affect Glibmm. 

Is there anything similar in glibmm/gtkmm

I'm using:
Glibmm: 2.64.2
Gtkmm: 3.24.2
