Thanks, finally we get an indication of what your code does and where.

I looked at it briefly, and the first thing I saw does not seem promising. 
Your algebraic calculations are enabled when behaved_p, which depends on 
buffer->text->monospace.  That field is set (unconditionally) to true in 
Fget_buffer_create, and reset only in only one place, in add_properties. 
Can you please elaborate a bit and explain why doing that would be TRT?
