Description
Starting with devtoolset-8, gcc-8 warns about catching polymorphic exceptions by value. As far as I understand, this is a bad coding practice in general.
The occurrence I've checked regarding ip_diffim build in afw/math/Statistics.h:115 is harmless, and I'll change it as part of DM-21422.
A list of places to check are grepped and attached.
