Hmm.  The changes between 12.1 and 12.2 were simply the addition of
qabs and qdiv; a change of the type fgets()'s second argument from
size_t to int; and posibly a change to vfprintf to handle
%ll[d,i,o,u,x] for long long integers.

I don't know how any these changes could cause the problems you are 
encountering.
