Hallo,

I am a C# newbie and have a problem. The attached example code (taken 
from a german magazine) does not compile using mcs 0.11. I get the 
following error.

(process:5050): ** ERROR **: file unicode.c: line 294 (iconv_get_length): 
should not be reached
aborting...
/usr/local/bin/mcs: line 2:  5050 Trace/Breakpoint ausgelöst  
/usr/local/bin/mono /usr/local/bin/mcs.exe $*

As far as I can remember, it compiled with a previous version of mcs 
(don't know which one it was)

Regards
Detlev
