I have increased some static data so maybe there is not enough memory on your 
machine.
Could you try decreasing some stack size. For instance:

   export TRAILSZ=10000
   export GLOBALSZ=20000

(use setenv under csh/tcsh)

then:

   make

Is it better ?

This is a new function (when implementing soft-cut I have modified deeply the 
code handling cut). However, there is nothing architecture-dependent in this 
code. The function is defined in EnginePl/wam_inst.c (thus in wam_inst.o and 
lib engine_pl.a)

Can you please:

   make distclean
   ./configure --disable-regs --with-c-flags=debug

When you obtain the error, could you check if the symbol is defined in the 
library ?

   cd EnginePl
   nm -gop libengine_pl.a | grep Pl_Get_Current_Choice

you should obtains something like

   libengine_pl.a:wam_inst.o:0000000000001570 T Pl_Get_Current_Choice

If you don't find a solution, could you give ma an access to your machine(s) 
(via ssh). With this I could fix the problem.
