Description David Binderman 2009-04-16 10:35:02 UTC 
I just tried to build Factory package idzebra-2.0.36-2.1
and the build said

bset.c:261: warning: operation on 'i' may be undefined

The source code is

            while ((i1=trav_BSet (sh, src, ++i)) == i)

I agree with the compiler. There is no guarantee
that the left side of a compare is evaluated before the
right side of a compare.  Suggest code rework.

Patch is now available from here: http://lists.indexdata.dk/pipermail/zebralist/2009-April/002187.html (thanks, Adam!).

Because this code fragment is only in use while debugging, I will wait for the next official idzebra update.
