We are using an Ultra-1, OS version = Solaris 2.6

I do not believe it is the actual call to NR__SVDFIT that is causing
IDL to halt because my colleague replaced SDVFIT with another 3rd
party fitting routine. His code still halts at some random point
in the fitting loop under 5.2, but appears work fine under 5.1.
Also, CNTRL-C usually does print the "Interrupt encountered" message
(but does not interrupt).
Memory usage is not an issue - the code is using only about 20 mb,
and is not allocating any more memory in the loop that causes
IDL to halt.
