Rainer, you probably know by now that this whole issue has nothing to do
at all with CLN? It seems like your patch breaks anything when using
-fno-exceptions. Attached is a trial program that only uses doubles and
some STL containers. (Sorry for not boiling it down from 100 to 10 lines,
I have unfortunately very little time right now.)
Can you confirm this? Otherwise we are back with the theory that my boxen
are broken / patched wrongly...
Regards
-richy.
