[R-SIG-Mac] R hangs in nls "port" routine

Hi,
I have a problem which is replicable, but I can only repeat it on an
Intel mac. I'm also uncertain if it is an R bug, or a bug in the
nl2sol routine that (I believe) is packaged within R.
Basically, on certain (large) datasets, and under certain specific
starting parameters, the nls routine hangs indefinitely when using
the "port" algorithm. The hanging R process then has to be killed
from the outside. Using "trace=TRUE" shows that it completes a single
iteration, then stops. This doesn't happen on PPC macs, or on the AMD
linux box that I have tried.
Since it is such a specific problem, I guess it is easiest if I try
to debug this myself, but I'm not sure how to do it. Could someone
possibly tell me what I need to do work out exactly what the problem is?
I've tried to narrow it down using "debug". It seems to hang after
the R_port_nlsb call, as follows:
Browse[1]>
debug: .Call(R_port_nlsb, m, d = rep(as.double(scale), length = length
(par)),
df = m$gradient(), iv, v, low, upp)
Browse[1]>
0 35.9307: -365.347 449.622 -1.57080 3.58496 0.0100000
0.500100
***hangs after outputting this first nls "trace" line***
I've then run
/Library/Frameworks/R.framework/Resources/R -d gdb
and interrupted + traced where it is hanging. I get the output pasted
below:
