Bug#851060: marked as pending

[Marcos Fouces]

Hello Axel

This compiler flag (-fno-strict-aliasing) is needed in libnids. You are 
right. I will revert this change in dsniff. I added the other flag (-g) 
in order to avoid creating an empty dbgsym package.


I cannot reproduce this bug in amd64 with the current libnids package 
version (1.21). In fact, dsniff works as expected with this testcase.


I built and installed libnids 1.24 (which fix another minor issue 
already solved in Ubuntu) with -fno-strict-aliasing. At least in amd64, 
dsniff still works as expected and i did not noticed any difference.


If the current maintainer of libnids (CC'ed) gives me permission, i can 
import the package to pkg-security team repo, upload my work and 
maintain (or co-maintain) it by now. This makes sense as dsniff seems to 
be the only reverse dependence of libnids.


I believe that in pkg-security team there are some people with access to 
armhf machines so testing should not be an issue. Unfortunately, i can 
do it myself.


Greetings,

Marcos

So it does not need those compiler flags in libnids but in dsniff?

Have you tested it on armhf?

Because I tried recompiling libnids with these flags and noticed no
difference. :-/

(But then again I could even reproduce the reported issue on amd64, so
I'm not 100% sure if I actually reproduced it correctly.)
