I'm sorry I wasn't following this thread closely for the last few days. 
I'm currently busy with a submission due in two weeks so I don't have 
continuous time to investigate the problem using GDB before Nov. 14.

I'm pretty certain it doesn't happen to a line spontaneously. I usually 
encounter this behavior (with a probability) when
1. after a font changes, like what the script I submitted did.
2. after switching to a different buffer, even if both buffers contains 
ligatures and uses the same font/fontset setting (though maybe one of 
the buffers contains certain characters with bold/italic/etc font 
attributes, I don't recall it exactly).
3. (maybe) after scrolling down/up the buffer into a position where a 
line contains ligatures appears.

Best,
Yixuan
