I am not sure if this is a bug in pari or gcc or if I am doing 
something wrong. 
While compiling pari with gcc-3.4.0, I see 

/usr/bin/gcc -c -O2 -DGCC_INLINE -Wall -Wno-implicit -fomit-frame-pointer
-march=i686   -I. -I../src/headers  -o buch2.o ../src/basemath/buch2.c
../src/basemath/buch2.c: In function `buchall':
../src/basemath/buch2.c:2925: warning: function called through a non-compatible
type
../src/basemath/buch2.c:2925: note: if this code is reached, the program will
abort

and like it says as soon as I type ./gp after the compilation completes
I get

  ***   bug in GP (Segmentation Fault), please report
  ***   Error in the PARI system. End of program.

I am attaching the output of strace if its helpful.
