Comment(by PolyBoRi):
Hi!
The following gives me a segfault:
{{{
from polybori import *
data=load_file("data/cook.py")
change_ordering(block_dp_asc)
append_ring_block(25)
groebner_basis(data.ideal, prot=True, heuristic=False)
}}}
{{{
------------------------------------------------------------
Unhandled SIGBUS: A bus error occured in SAGE.
This probably occured because a *compiled* component
of SAGE has a bug in it (typically accessing invalid memory)
or is not properly wrapped with _sig_on, _sig_off.
You might want to run SAGE under gdb with 'sage -gdb' to debug this.
SAGE will now terminate (sorry).
------------------------------------------------------------
sage.bin(2141) malloc: *** error for object 0x10ad1f000: incorrect
checksum for freed object - object was probably modified after being
freed.
*** set a breakpoint in malloc_error_break to debug
sage.bin(2141) malloc: *** error for object 0x10ad52000: incorrect
checksum for freed object - object was probably modified after being
freed.
*** set a breakpoint in malloc_error_break to debug
sage.bin(2141) malloc: *** error for object 0x10ad53800: incorrect

}}}
Used it on Mac OS X 10.5 64BIT.
