Hello,
I think I found a bug in the current 6.0 branch:
a=uint8(rand(2,2)*255);
b=rand(2,2);
//let's be sure not to divide by 0
while or(b==0)
b=rand(2,2);
end
//adios amigo: Segmentation fault (core dumped)
a./b
Dividing a uint8 matrix by a double matrix is always causing a
segfault on my machine.
Can you reproduce this bug on your machine?
Does anyone know whether it's a known bug or not?
I have found :
https://antispam.utc.fr/proxy/2/c3RlcGhhbmUubW90dGVsZXRAdXRjLmZy/bugzilla.scilab.org/show_bug.cgi?id=15716
but it is not exactly the same (I don't do any division by zero,
just element-wise division.
Cheers,
Antoine
Hello Antoine,
Surely, this is a bug, but what type do you expect for the (eventual)
result ?
I reported a bug: https://bugzilla.scilab.org/show_bug.cgi?id=15759
Can some or you try my test script for your OS/scilab version?
Weirdly enough, under scilab 5.5.2, there is no segfault, but scilab
complains about a division by zero (whereas there is no division by
zero).
Also, division (not element-wise division) gives a funny result, both
for 5.5.2 and the current master:
a=uint8(rand(2,2)*255);
b=rand(2,2);
//let's be sure not to divide by 0
while or(b==0)
b=rand(2,2);
end
//just a division :
// master and scilab-6.0 : Operator / : Error -1 not yet managed.
// 5.5.2 : !--error 26
// Too complex recursion! (recursion tables are full)
// at line 9 of function %i_r_i called by : ...
a/b
