Divisors bug in GP

[Phil Carmody <thefatphil@yahoo.co.uk>]

I'm using an AFAICT undocumented call to divisors() with a 
factorisation as a parameter, rather than a single number. 
If this interface doesn't officially exist, I'd like to 
request that it be realised, as I could make very good use 
of it presently.

Anyway, it seems to 'break' its parameter.

phil@megaspaz:Oalpha-gmp-gcc$ ./gp-sta -q
(11:17) gp > f1=factor(1234);
(11:18) gp > f2=factor(1234567);
(11:18) gp > f3=concat(Mat(concat(f1[,1],f2[,1])),Mat(concat(f1[,2],f2[,2])));
(11:18) gp > divisors(f3);
(11:18) gp > f3
  ***   bug in GP (Segmentation Fault), please report
(11:18) gp > f3=1
  ***   bug in GP (Segmentation Fault), please report
(11:18) gp > kill(f3);
  *** kill: bug in GP (Segmentation Fault), please report
