deleting rows from sparse matrices leads to seg fault sometimes

[Lev]

Hi All,

I have found a bug in which octave to segfault but cannot identify the
reason of it.
I saved the context in a file but cannot rewind the segfault by replaying
it.

/
while(true)
    ....
    uec = sum(uis,2);
7
    inx = find( uec< limit );
8
    save aa.dat
    uis(inx,:)=[];  % throws segfault here !
9
    ....

end
/

After having this code failed I made a following:
/
load aa.dat
uis(inx,:)=[];  
/
and it doesn't fail.

Does anybody have an idea how to debug this it doesn't segfaultcase?
Cheers,
Lev
