colleagues,<br><br>i believe this is another ripple effect of ‘bogus’ LNK values<br>sneaking into MRSs; see:<br><br> <a href="http://lists.delph-in.net/archives/developers/2012/001696.html">http://lists.delph-in.net/archives/developers/2012/001696.html</a><br>
<br>the problem was addressed in the LOGON trunk last fall:<br><br>------------------------------------------------------------------------<br>r11685 | oe | 2012-08-12 10:32:37 +0200 (Sun, 12 Aug 2012) | 1 line<br><br>make MRS output and input more robust (in terms of bogus LNK values)<br>
------------------------------------------------------------------------<br><br>but it appears i have yet to promote that change into the LKB<br>trunk, i.e. even latest LinGO builds may still have the issue. i<br>will aim to synchronize (what should only be small differences<br>
