The interesting bit is the end of your output. We stick in the main loop but 
never get to any of your new log statements. This should mean that we reach one 
of the continue statements further up in the code. Could you please add a log 
output just before each of the continue lines? For me they are on the lines 862 
and 868.
All of this is based on the asumption that the "Main glyph layout loop. i:" 
output comes from inside the main loop, that is from below line 732.
