>From the in-tree test file, test cases 15, 19, 20, 53 and 54 all
involve 'Ra'. Case 5 (കാര്‍ക്കോടകന്‍) involves 'RA+ZWJ' in the middle
of the word. At present all are failing (interestingly, case 5 was
fine during the crash ;-)).
'RA' in Malayalam needs to be treated as if it is post-base. I'm
attaching images a simple test case for 'ക്ത്ര' using Rachana font
(hb-view and pango-view outputs).
Meanwhile, the latest commits segfaults again like datao zhang reported.

Also noticed that post-base 'LA' is not correctly rendered for 'സ്പ്ലേ'.
