[Dr . Jürgen Sauermann]

Hi Jerome,

I may have found the fault, please check SVN 1157.

Thanks,

Hi Jerome,

I could not find anything wrong; the warning may or may not be bogus.

I nevertheless made a change to narrow down the problem and to make the
array subscript more explicit. Unfortunately the warnings below do not provide
sufficient information as to where exactly the problem was detected by the compiler.

Please let me know if the warning occurs also in SVN 1156.

Thanks,
Jürgen
