Thx, I was just about to reply something similar. :-D
Sudip, maybe you know about this already, but in case you don't, here is
a quick tip that might be useful for you: in cases like this it's often
wise to search for earlier reports on lore using an even more
abbreviated commit-id followed by a wildcard (e.g. "9c66dc94*"). That at
least was how I found the fix quickly.
Ciao, Thorsten
