Of course, you people would have noticed that I have by default
commented out the line with Brahmi text, which is why it does not
segfault as I have given it to you. To reproduce the segfault, remove
the %.

I also tested with a version of the font with OT tables added:


The curious thing is that now with this TTF there is no more segfault.
With /GR not included, there is no rendering and the glyphs are just
placed there. (I tried script=brah and script=deva to induce OT
behaviour but no luck.) With /GR included, actually I'm getting some
rendering, but there are still some boxes. (There is a warning of a
bad CMAP mapping -- I wonder.) But since this is a version with OT
tables I'm not sure if the renderer being used is Gr or OT.

Very confusing... :-(
