2.0.9 comments/bugs

["John Cremona (Maths)" <cremona@noether.ex.ac.uk>]

Some things about testing 2.0.9, both on a PentiumII and on an alpha.

1. "make" in examples gives compiler warning and the executable
   crashes:

omega[374]%make
/usr/bin/gcc -c -O2   -I. -I/usr/local/include/pari matexp.c
/usr/bin/gcc -o matexp-dyn -O2   -Xlinker -export-dynamic matexp.o -Xlinker -rpath -Xlinker  /usr/local/lib -L/usr/local/lib -lpari -lm 
matexp.o: In function `main':
matexp.c(.text+0x584): the `gets' function is dangerous and should not be used.
omega[375]%matexp-dyn
precision of the computation in decimal digits? 30
input your matrix in GP format:
[1,0;0,1]           
  ***   segmentation fault: bug in PARI or calling program.


  ***   Error in the PARI system. End of program.


2. Copying examples/Inputrc to ~/.inputrc causes problems when
   running under emacs (sometimes I do, sometimes I don't...).
   Namely,  the automatic closing bracket insertion happens but
   invisibly which is rather confusing.

3. factorint(2^128+1) causes 

  *** segmentation fault: bug in GP (please report)

The alpha has the following benchmarks:

alpha21164   533Mhz    Linux 2.0.34  gcc X11 ?dl2?    6511    6685   2.0.9

(I don't know the answer to the dl2 question...)
