+Summary: mcs fails using certain optimizations for mini
+
+Description of Problem: 
+ 
+I did not notice this problem when running small test programs with mini, but when 
+I used ran mcs.exe under mini and tried to compile a very large program like Qt#, I 
+ran into some problems with some optimization options. 
+ 
+The basic command line was 
+ 
+mini -O=$opt /usr/local/bin/mcs.exe -nowarn:0108 -nowarn:0114 -target:library 
+-optimize+ $list 
+ 
+where $opt was the particular optimization selected and $list was the list of source 
+files. 
+ 
+With $opt=deadce, compilation aborted with 
+** ERROR **: unknown operator: local 
+aborting... 
+Aborted 
+ 
+With $opt=shared, mcs did not even start the compilation, but instead printed its 
+option summary. I believe that the command arguments somehow got corrupted. 
+ 
+With $opt=all, I got a different error: 
+Exception caught by the compiler while compiling: 
+   Block that caused the problem begin at: QtSupport.cs: (335) 
+ 
+Unhandled Exception: System.NullReferenceException: A null value was found where 
+an object instance was required 
+ 
+If I used all optimization options except deadce and shared, so $opt= 
+peephole,branch,inline,cfold,consprop,copyprop,linears,cmov,sched,instrins,tailc,loop,fcmov 
+compilation was successful. 
+ 
+Steps to reproduce the problem: 
+1. See above.

+How often does this happen?

+Always

+know.
