GMP memory allocation and Macaulay2

[Doug Torrance <dtorrance@piedmont.edu>]

Hello!

Currently, PARI sets the GMP memory allocation functions in 
pari_kernel_init().  However, this may cause problems for applications 
which use both the PARI and GMP libraries such as Macaulay2.  Building 
Macaulay2 against unpatched GMP and PARI libraries causes segmentation 
faults.

Currently, Macaulay2 builds its own GMP (actually MPIR, a drop-in 
replacement) in which mp_set_memory_functions() does nothing.  This is 
not ideal, however.  For example, this is the main problem keeping 
Macaulay2 out of Debian, as it cannot be built with the current Debian 
GMP and PARI packages.  (See [1] for some discussion on this matter.)

Would it be possible to remove the calls to mp_set_memory_functions() 
from PARI?

Thanks!
Doug Torrance
