Eli/Andreas,
Here are a few more things I tried.
1. Removed the current libotf and libm17n-flt libraries, installed the
versions
libm17n-flt                                    1.6.4-2ubuntu1
libotf0:amd64                                  0.9.13-3
Configured and compiled emacs.  This crashes as well.

2. If I set the default font to Noto-Kannada and open the file, It has no
issues but crashes as soon as I start adding English words.

3. The crash occurs only when a certain combination of Kannada chars are
present along with English characters/Words.

Let me know if you need additional data.

There were no such issues with a variant of ubuntu-14.04.

Regards,
Reddy
