Yes, search for E6047, or 'storage index out of range' in the reports I
uploaded a couple of months ago -
https://github.com/HinTak/FontVal-Tests-at-10pt/blob/fedora/fonts/lohit-devanagari/Lohit-Devanagari.ttf.xml
Same detailed information there...
I suppose I should file a bug with fedora...

The font is hinted with my ttfautohint program but using an older,
buggy version: For example, MS Visual TrueType reports
Glyph ID 2
Critical Error:
Inst: WS Storage index out of range. Index = 96, Range = 0 .. 95
At ByteOffset: 223 Of function: 4
In other words, Windows stops hinting and displays the glyph unhinted.
FreeType, on the other hand, tries to continue with hinting – in many
situations this is a good decision, but here we have a case where the
result is bad.
BTW, using the current version of Lohit Devanagari (2.95.4), which has
been hinted with a newer version of ttfautohint, the rendering is OK.
