+mini --trace t1.exe 
+to see the unaligned stack access problem shown above. 
+Some additional information: 
+I'm seen two symptoms of problems when trying to run Qt# apps. One is the 
+unaligned stack access with --trace, and another is string corruption. Strings 
+seem be getting corrupted into other strings: instead of getting turned into 
+garbage, strings are getting changed into other strings that are allocated in the 
+heap. For example, near the top, notice how "destroyed()" instead got 
+corrupted into "Void Emit". 
+This corruption does not occur with GC disabled. Also, Gonzalo suggested 
+invoking mini using 
+mini -v -v -v -v t1.exe > verbose.txt 
+and the corruption did not occur in that case either. 
+These problems are very difficult to narrow down. When I tried adding 
+WriteLine() to determine where some of the problems happened, some of the 
+problems actually disappeared (to be replaced by other problems in other
