I had some strange problems with modreg: sometimes functions
hang in an infinite loop, consuming 100% CPU time. Especially
when update()ing models (as in example(ppr)) with sm.method="gcv"
I found that if I repeated the call after I did interrupt the hang,
it ran to completion.
After some lengthy debugging I could track down this problem:
sinerp.f, line 22--24 read:
wjm3(1)=0d0
wjm3(2)=0d0
wjm3(1)=0d0
This leaves wjm3(3) uninitialized. So after changing these lines to
wjm3(1)=0d0
wjm3(2)=0d0
wjm3(3)=0d0
the bug was gone.
