New description:
See attachment. The following program crashes with segmentation fault on
Sage 4.6 / Linux Ubuntu 10.04 x86 32-bit
$ sage essai1.sage
[...]
block 1
is not sdp
echelonizing
echelonized
------------------------------------------------------------
Unhandled SIGSEGV: A segmentation fault occurred in Sage.
This probably occurred 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).
